Using a checkbox in a grid component
Hello
Does any one have a short recipe how to use a checkbox in a grid
component?
What I need to do is fairly simple - let the use select (for example)
three of five available options presented in a grid component, and
submit their selections, which are then processed. A good example
would be a "remove" checkbox on a list of items in a shopping cart,
where the items are are only in the user's session so database IDs
won't do.
I've tried looking through the wiki, searching google, searching the
mailing list with google, and looking through the 'Tapestry 5 Building
Web Applications' book which I bought as a PDF, but alas, I can't find
find a simple recipe for doing this.
I'd like to use the Grid because the data will be fairly complex (it
isn't for the time being, once I get this technique functional it will
be). I'd like the selection to change a value in the underlying POJO
(e.g. Pojo.selected) that's backing the Grid. I have been unable to
get this anywhere near any semblance of "working". Therefore
currently any sort of technique that could possibly work would be
appreciated, for example to have an List<Pojo> originalList and
List<Pojo> selectedList - I've tried to see what convention might give
me that behaviour but so far, been unable to uncover it.

Olá Thiago :) and Hello Antalk
I've just looked to the demo, and it appears to be exactly what I'm looking
for.
Thank you both for your help
Cheers,

You could checkout my Tapestry Module : Weaves, it has a 'improved' grid
component with paging and checkboxes per row and also a 'checkall' box.
See: http://intercommitweavesdemo.intercommit.cloudbees.net/pagedgriddemo
for demo

Re: Using a checkbox in a grid component
Posted by Paulo Ricardo Ribeiro <pa...@gmail.com>.
Hello,
I'm trying to add a "Select All / Select None" button at the end (or top) of
the grid.
I'll, probably create a mixin to do so, but, since i don't want to "reinvent
the wheel", I'm wondering if there's a simple way to do it.
Cheers,
Paulo Ricardo

Here's a working example of a similar technique.

RE: Using a checkbox in a grid component
Posted by Alfie Kirkpatrick <Al...@ioko.com>.
As Sebastian points out if the boolean selected field is part of your
pojo it is trivial to bind this to a checkbox in the grid. This was my
initial approach for simplicity but in my case the pojos were Hibernate
entities and I didn't want this field to be persisted or to clutter up
the entity as a transient field, so I went with a different approach
which might work for you...
I created a session-persisted hashset in my page where the elements are
the ids of the entities being selected (you can use the items themselves
if they support hashcode/equals properly).
My code looked something like this:
MyPage.java
-----------
private HashSet<String> selectedSet=new HashSet<String>();
public boolean getCurrentSelected() {
return selectedSet.contains(current.getId());
}
public void setCurrentSelected(boolean value) {
if ( value ) {
selectedSet.add(current.getId());
} else {
selectedSet.remove(current.getId());
}
}
MyPage.tml
----------
<t:grid t:id="selectProgrammesGrid"
source="availsList"
row="current"
add="select">
<p:selectcell>
<t:checkbox value="currentSelected"/>
</p:selectcell>
</t:grid>
Hope it helps, I thought it was rather tidy!
Alfie.

No difference. <t:parameter name="property"> was the first syntax
provided. The <p:propertyName> is the new one, added in 5.1.0.x.

Yes indeed.
In the end I got this to work
<t:grid source="contacts" row="contact">
<p:selectedcell>
<t:checkbox t:id="selected" value="contact.selected" />
</p:selectedcell>
</t:grid>
Which is remarkably similar to what I had in the first place. So I
don't really know what I did wrong in the first instance that led me
to bolt down a rabbit hole.
BTW Is there any effective difference in using the <t:parameter
name="propertynameCell"> style versus the <p:propertynameCell> style
of controlling the cell render?

You might not even need any chenillekit on this. I use:

<t:checkbox t:id="name" t:value="row.name"/>
</t:parameter>

extract of the template
