checkbox widget with datatype vector
Hi,
I have a shopping cart system which enables a user to select a number of
items from their cart and delete them at the same time. This was working
perfectly before I chnaged everything to widgets because I need to use ajax.
What is happening now is that no matter how many items you select to delete,
only one item is ever deleted at a time. Now I suspect that the problem lays
with the datatype being used in fd:
<fd:field id="delItem" required="true|false">
<fd:datatype base="string"/> // I tried boolean and nothing was being
deleted
</fd:field>
widget definition is:
<ft:widget id= "delItem">
<fi:styling value="${orderitem.getID()}" type="checkbox"/>
</ft:widget>
flow:
delItems = bizData.delItem;
var items = new java.util.Vector();
if (parseInt(bizData.quantity) || delItems != null) {
try {
if (delItems != null) {
if (delItems.iterator) { // A list of delItems have been
selected to be deleted.
items.addAll(delItems);
deleteOrderItem2(items);
} else { //A single delItem has been selected to be
deleted.
items.add(delItems);
deleteOrderItem2(items);
}
}
Any ideas what I am missing here?

Hi Jason,
on further investigation I see that I have made a mistake. The previous
code snippet should have read:
if(java.lang.Boolean.TRUE.equals(row.lookupWidget("delete").value)) {
itemsToDelete.add(row.lookupWidget("id").value); //add item to delete
deleteOrderItem2(itemsToDelete);
//now delete item row from repeater
}
Once I have the itemID I add it to the vector and send that to my delete
orderItem function. What I then want to do is to delete the actual row from
the table associaated with the orderItem ID. How do I do that in flow? I
also have a snippet which handles adding orderItems:
if (parseInt(bizData.quantity)) { //Add a row if need be
//add a row and an item to the orderitem
addOrderItem(bizData.quantity, bizData.orderID,
bizData.stockID);
//Now add this item to the repeater
}
and again, once the orderitem object has been updated I now want to add that
item to the repeater. I tried:
//Now add this item to the repeater
form.lookupWidget ('items')
.addRow()
.getChild('id').value = orderitem.getID()
.getChild('artistName').value = orderitem.getArtistName()
.getChild('itemTitle').value = orderitem.getStock
().getItemTitle()
.getChild('amount').value = orderitem.getAmount()
.getChild('price').value = orderitem.getPrice()
but get an 'TypeError: getChild is not a function.'
So how do I do also add a row item to a repeater from within flow?

Hi Jason,
all is working now! I forgot to specify form.load(bean) before the
form.showform!!
Many many thanks for your patience and help

Hi Jason,
we're nearly there! I've created the binding document, implemented it into
flow but no rows are being displayed when I update the order object!! What
am I overlooking?
flow:
var form = new Form("forms/artistOrder_new.xml");
form.createBinding("binding/artistOrder_binding.xml");
form.showForm("viewform-artistOrder_new.xml",{"artistID":artistID,"artist_name":artist_name,"artist_info":artist_info,"track_info":track_info,"track_location":track_location,"track_type":track_type,"stock_code":stock_code,"userGlobal":userGlobal,"neworder":neworder,"stock_price":stock_price,"msg":delItems,"msg2":msg2,

if (parseInt(bizData.quantity) || repeaterSize != 0) {
try {
if (repeaterSize != 0) { //Delete a row if need be
//delete a row and an item from the orderitem
for(var i=0; i < repeater.getSize(); i++) { //loop over
the rows
var row = repeater.getRow(i);
if(java.lang.Boolean.TRUE.equals(row.lookupWidget("delete").value))
{ //is the booleanfield checked?
itemsToDelete.add(row.lookupWidget("id").value);
//add the item id to delete from widget
deleteOrderItem2(itemsToDelete);

form.load(neworder);
}

Like I mentioned before, I think the easiest way to load data into the
repeater is with a fb:simple-repeater binding. I presume you're not
familiar with the binding framework; it's basically a way to define (in
an XML syntax) how to map values between a business object and the form
object's widgets. See the documentation:
http://cocoon.apache.org/2.1/userdocs/binding.html
There's a special binding type called fb:simple-repeater (named such
since it's much simpler than the full fb:repeater binding, but should be
sufficient for your case) that lets you bind values from a Collection,
Array, or anything else that JXPath can iterate over, to and from a
fd:repeater widget and all its children. Something like:
In a binding file:
...
<fb:simple-repeater id="items" parent-path="." row-path="orderItems"
direction="load">
<fb:value id="id" path="ID" />
<fb:value id="artistName" path="..." />
...
</fb:simple-repeater>
...
In your flow:
form.createBinding("path/to/binding-file.xml"); //creates the binding
...
form.load(neworder); //loads the data into the form using the binding
That's it. You can call form.load() as many times in your flow as you
want, such as after you delete items or a new item is added. As long as
the orderItems list contains the up-to-date list of items, the repeater
will be updated to match.

Hi Jason,
first off I have to say I appreciate the time you put into helping me grasp
these concepts, much appreciated.
Ok, so I have in jx file:
<ft:repeater-rows>
<tr>
<td width="8" class="normaltext"></td>
<td class="normaltext"><ft:widget id="id" /></td>
<td width="8" class="normaltext"></td>
<td class="normaltext"><ft:widget id="artistName"
/></td>
<td width="8" class="normaltext"></td>
<td class="normaltext"><ft:widget id="itemTitle"
/></td>
<td class="normaltext"></td>
<td class="normaltext"><ft:widget id="amount"
/></td>
<td class="normaltext"></td>
<td class="normaltext"><ft:widget id="price"
/>.00</td>
<td class="normaltext"></td>
<td class="normaltext"><ft:widget id="delete"
/></td>
</tr>
</ft:repeater-rows>
and in my validation:
<fd:repeater id="items" initial-size="0">
<fd:widgets>
<fd:output id="id">
<fd:datatype base="string" />
</fd:output>
<fd:output id="artistName">
<fd:datatype base="string" />
</fd:output>
<fd:output id="itemTitle">
<fd:datatype base="string" />
</fd:output>
<fd:output id="amount">
<fd:datatype base="string" />
</fd:output>
<fd:output id="price">
<fd:datatype base="string" />
</fd:output>
<fd:booleanfield id="delete" />
</fd:widgets>
</fd:repeater>
and in my flow:
if (repeaterSize != 0) { //Delete a row if need be
//delete a row and an item from the orderitem
for(var i=0; i < repeater.getSize(); i++) { //loop over
the rows
var row = repeater.getRow(i);
if(java.lang.Boolean.TRUE.equals(row.lookupWidget("delete").value))
{ //is the booleanfield checked?
itemsToDelete.add(row.lookupWidget("id").value);
//add the item id to delete from widget
//now delete item from orderitems object
items.add(row.lookupWidget("id").value);
deleteOrderItem2(items);
}
}
}
if (parseInt(bizData.quantity)) { //Add a row if need be
//add a row and an item to the orderitem
addOrderItem(bizData.quantity, bizData.orderID,
bizData.stockID);
// add values to repeater widgets, and then add row to
repeater-rows
}
So how in flow do I add values to each of the widgets, (id, artistName, etc
etc etc), in the repeater, and then add that row to <ft:repeater-rows>?

Small correction... the above line should probably be something more like:
if(java.lang.Boolean.TRUE.equals(row.lookupWidget("delete").value)) {
Datatype conversion between Java and JS can be tricky at times. ;-)

When you load data into the repeater (a fb:simple-repeater binding is
probably the easiest way) it automatically works that way; it displays
the rows it contains and nothing more.

I think you're really mixing concepts up. You're wanting to put
multiple values into a widget (fd:field) that *by definition* has a
single value. There's a special kind of field designed specifically for
holding multiple values: *multivaluefield*! So if you want one value
use fd:field, if you want multiple use fd:multivaluefield, it's that simple.
So anyway, let's get back to repeaters and try to switch your thinking a
little bit...
Rather than having a single widget with multiple values, you will have
multiple repeater rows each with a fd:booleanfield widget which acts as
a flag that the item represented by that row should be deleted:
<fd:repeater id="items">
<fd:widgets>
<fd:output id="id">
<fd:datatype base="integer" />
</fd:output>
<fd:output id="artistName">
<fd:datatype base="string" />
</fd:output>
...
<fd:booleanfield id="delete" />
</fd:widgets>
</fd:repeater>
Then afterward in your flow, you can just iterate over all of the
repeater's rows, see which ones have their booleanfield checked, and
build your Vector/Collection from them. Something like:
var itemsToDelete = new java.util.Vector();
var repeater = form.lookupWidget("items");
for(var i=0; i<repeater.getSize(); i++) { //loop over the rows
var row = repeater.getRow(i);
if(row.lookupWidget("delete").value) { //is the booleanfield checked?
itemsToDelete.add(row.lookupWidget("id").value); //add the item id
}
}
Besides the template, which is straightforward, that should be it.

Ok. So the first issue to address is how to tell the repeater to repeat only
as many times as there are items in the orderItem object? Secondly, let's
say that I have 2 orderItems which read by the repeater will give me 2 rows.
So each row will comprise a check box called delItem (which when selected
enables that row to be deleted), this brings us right back to the problem we
had at the begining, what datatype to give delItem so that in flow delItem
is recognised as a vector, which it would be if I were to defined using a
conventional, non widget, <input type="checkbox /> html approach? I have an
fd:datatype for delItem as string at the moment:
<fd:field id="delItem">
<fd:datatype base="string"/>
</fd:field>
<ft:widget id= "delItem">
<fi:styling value="${orderitem.getID()}" type="checkbox"/>
</ft:widget>
and no matter how many delItems you select, only one is ever deleted at a
time! Is there no way to introduce datatypes, for example
java.Util.Vector!?! This would resolve the problem I am having without
the need for
repeaters or multivaluefields.

Ah, now I see. If I'd known this was what you were going for I wouldn't
have recommended the selection-list approach.
I think you have a few choices:
1) Create your own custom styling for fi:multivaluefield that displays
only a single checkbox where you set its value, sort of like you were
doing before.
2) Bypass the ft:widget call altogether and just write out your own
<input type="checkbox" name="delItem" value="${...}" /> for each row.
3) Use a repeater rather than the JX loop. It sounds like you were
trying to enable AJAX for this form, so this may be your best bet.
Either of the first two choices above would be difficult to make work
with CForms' AJAX framework. Personally I think this is the cleanest
approach.

Hi,
all is working now, but.......
Ok, so I have a jx loop which pulls in all of the orderitem details required
to be displayed to a user:
<jx:forEach var="orderitem" items="${neworder.getOrderItems()}">
<tr>
<td width="8" class="normaltext"></td>
<td class="normaltext">${orderitem.getID()}</td>
<td width="8" class="normaltext"></td>
<td class="normaltext">${orderitem.getArtistName
()}</td>
<td width="8" class="normaltext"></td>
<td
class="normaltext">${orderitem.getStock().getItemTitle()}</td>
<td class="normaltext"></td>
<td class="normaltext">${orderitem.getAmount()}</td>
<td class="normaltext"></td>
<td class="normaltext">${orderitem.getPrice()}.00</td>
<td class="normaltext"></td>
<td class="normaltext">
<ft:widget id= "delItem">
<fi:styling list-type="checkbox"/>
//MultiValueField
</ft:widget>
</td>
</tr>
</jx:forEach>
<fd:multivaluefield id="delItem">
<fd:datatype base="string"/>
<fd:selection-list nullable="false" type="flow-jxpath"
list-path="neworder/orderItems" value-path="ID" label-path="''" />
</fd:multivaluefield>
Having the delItem widget in the table now means that for every item in the
users cart, 1 extra checkbox will be displayed for that orderitem, because I
basically have a loop within a loop! So basically what I need is a widget
that will allow me to create a table like the one above, minus the final
mulivaluefield widget, pulling in all orderitems from one source instead of
two sources like above. Is this possible?
The solution I had before using jx to iterate through an object does not
work as there is no fd:validation which can handle a number of fields with
the same id that is not generated by a multivaluefield. Also the
multvaluefield option does not work as it will give me a list of checkboxes
based on the number of items within an object. There is then no way to marry
the checkboxes with other items, as I have, displayed by a jx loop which
itself iterates through the same object as the multivaluefield. Any solution
here at all?

Ok,
what I needed was:
form.lookupWidget("widgetid").value
So what gives with var model = form.getModel()? Does getModel not pick up
all the widgets, and model.widgetid not simply pull the value out of the
widget?

Re: checkbox widget with datatype vector
Posted by Andrew <an...@gmail.com>.
Hi,
var model = form.getModel();
var bizData = {"next" : model.next, "delItem" : model.delItem,
"quantity" : model.quantity, "orderID" : model.orderID, "stockID" :
model.stockID}
var confirmOrder = bizData.next;
var delItems2 = bizData.delItem; //The list of selected checkboxes
var delItems = java.util.Arrays.asList(delItems2);
The above gives me the follwoing error:
Cannot convert
org.apache.cocoon.forms.flow.javascript.ScriptableWidget@b4216d to
java.lang.Object[]
So when I do:
var delItems = java.util.Arrays.asList(delItems2.getValue());
I get the follwoing error message:
getValue is not a function.
What am I missing here?

Sorry, I'm working with an incomplete picture here... I don't know what
bizData is or what bizData.delItem returns. If it's the actual widget
then yes, you should be able to do .value to get its value. That value
will be a Java String[] array, so if you have to get that into a Vector
or Collection to satisfy whatever API you're passing it to then you'll
need a conversion something like what I wrote in my previous reply.

Hi Jason,
Interesting, so how do users know what items they're deleting if you

Believe me you me, I nearly choked at the final design cost of my website!
Suffice to say a lovely table format was designed whereby the orderId,
artist name, title, qty, price, and then the delete checkbox are all
lovingly displayed to the end user. What is not needed on the end of that
row is the orderid again ;-)
Anyway, if that's really what you need then you can override the styling

As delItems is now actually a widget, why can I not do this to extract the
value of the widget?:
delItems = bizData.delItem.value;

Or something you might try first -- I haven't tried this so I don't know

resolve the label, feed it an XPath expression that always returns an
empty string. Maybe like label-path="''"?

Does it have to be a java.util.Vector specifically or will any
java.util.Collection or List do? If the latter then you can just do:
var items = java.util.Arrays.asList(delItems); //returns java.util.List
If you really need a Vector you can then create one from that List:
var itemsVector = new java.util.Vector(items);

Unfortunately it is bit of a design issue and I do not need it displayed on
the screen. Is there no way at all this value can be optional?!
Should be list-type="checkbox".
Spot on again, thanks. When I select a value to be deleted none of them are
being deleted. If memory serves me correctly I need to convert the array
type to a collection and then obtain an iterator on the collection right?
Again the flow code is unchanged:
delItems = bizData.delItem ;
var items = new java.util.Vector();
if (parseInt(bizData.quantity) || delItems != null) {
try {
if (delItems != null) {
if (delItems.iterator) { // A list of delItems have been
selected to be deleted.

Sorry, I thought it was optional. But no big deal, just set it to the
same as your value-path.

Check the docs:
http://cocoon.apache.org/2.1/userdocs/widgets/widget_multivaluefield.html
Should be list-type="checkbox".

Hi Jason,
<fd:selection-list type="flow-jxpath"
> list-path="neworder/orderItems" value-path="ID"
> label-path="(optional path to display label)" />
how do I manage to avoid having to use the label-path attribute? Anytime I
try to keep it out I get an eror message saying that it is required! With it
in I get a selection list instead of check boxes. My widget code is as
follows:
widget:
<ft:widget id= "delItem">
<fi:styling type="checkbox"/>
</ft:widget>
validation:
<fd:multivaluefield id="delItem">
<fd:datatype base="string"/>
<fd:selection-list type="flow-jxpath" list-path="neworder/orderItems"
value-path="ID" />
</fd:multivaluefield>

Andrew

Use the flow-jxpath selection list type as described on
http://cocoon.apache.org/2.1/userdocs/widgetconcepts/selectionlists.html.
Something like:
<fd:selection-list type="flow-jxpath"
list-path="neworder/orderItems" value-path="ID"
label-path="(optional path to display label)" />

Hi,
is there a way I can build my list from accesing the required order class I
use in selection-list? In my jx I do:
<jx:forEach var="orderitem" items="${neworder.getOrderItems()}">
and then pull out the id I want in the checkbox as so:
<fi:styling value="${orderitem.getID()}" type="checkbox"/>
So would I be able to do:
selection-list src="neworder.getOrderItems().get()" ? And if so how would
the selection-list know how to iterate through the object to pull out all
orderitem id's?

that is correct. What benefit would there be to using a repeater over the
method I am using?
I think just using an fd:multivaluefield should work;
No. Unfortunately this does not work, as it seems that at least one instance
of the widget is required, where as in my case you will always start with
zero items in a shopping cart, so there would be nothing to selectin the
first instance. I also noticed that my checkbox was overwritten with a
selection list box which is not what I want at all. I used the following:
widget:
<ft:widget id= "delItem">
<fi:styling value="${orderitem.getID()}" type="checkbox"/>
</ft:widget>
validation form:
<fd:multivaluefield id="delItem">
<fd:datatype base="string"/>
</fd:multivaluefield>

A repeater in itself, also, is of no use to me as this, as you know, only
allows me to repeat a number of other widgets an unspecified amount of
times.

I'm guessing that this is displayed multiple times using a JX forEach
loop, rather than a repeater?
I think just using an fd:multivaluefield should work; the widget will
take care of parsing the multiple values from the request into an Array
object. That would also simplify your flowscript since you'll always
get an Array rather than having to do the if/else for single vs.
multiple selection.
However, usually multivaluefield widgets have their individual checkbox
items generated from a selection-list, rather than by iterating manually
and calling ft:widget multiple times with different values. I'm not
sure how your approach will work with AJAX updates since it's a
nonstandard use of the widget.

Re: checkbox widget with datatype vector

Hi,
I have managed to track down the email I first posted to the group
concerning this issue in 2004!:
http://mail-archives.apache.org/mod_mbox/cocoon-users/200411.mbox/%3Cs18f3876.079@cs-emo.csir.co.za%3E
The only thing I have changed, like I said earlier, is that I have now
implemented a widget system with required fields and I suspect that it is
the datatype declaration I have assigned to the widget that is causing the
problem here.
Any pointer will be most welcome.
regards
Andrew
