Adding Component at Runtime
Hi all,
Is it possible to add component(say CheckBox) at runtime.
Regards
Ashish

I think you can accomplish what you want using Block and RenderBlock
components. Check out

It sounds like you can do this with a simple Foreach, something like the
following.
<tr jwcid="@Foreach" source="ognl:listModel" element="tr">
<td><input type="checkbox" jwcid="@CheckBox"
selected="ognl:someProperty"></td>
</tr>

Ashish, wouldn't this work?
<span jwcid="@Conditional" condition="ognl:List.size()==2">
<!-- insert your 2 checkbox here -->
</span>
But, are you trying to really do a loop? Are you trying to take a list and then display a check box for each item in the list? In
other words, if the list has 3 items, you want 3 checkboxes, if the list has 7 items, then 7 checkboxes, and so on. In that case you
should be using Foreach.
For example (I'm just using an insert here, not a checkbox):
in your jwc:
<component id="jobOpportunities" type="Foreach">
<binding name="source" expression="jobOpportunities"/>
<binding name="value" expression="jobOpportunity"/>
</component>
<component id="jobTitle" type="Insert">
<binding name="value" expression="jobOpportunity.jobTitle"/>
</component>
in your html:
<tr jwcid="jobOpportunities" element="tr">
<td><span jwcid="jobTitle">Manager</span></td>
</tr>

I have done something a little different, as well (but perhaps I'm just
reinventing the wheel).
To avoid having to write the getter and setter for the checkbox, I've
created a class that is something like a Map, but ensures that for any
key an object is returned that supports isSelected() and setSelected().
This allows one to bind things this way (assuming that "currentLocale"
is set to the current value in the Foreach or ListEdit):
<component id="checkbox" type="Checkbox">
<binding name="selected"
expression="selectedLocales.get(currentLocale).selected"/>
</component>
...
<property-specification name="selectedLocales"
type="SelectedSet" initial-value="new SelectedSet()"/>
and the SelectedSet class then allows getting the selected set via:
getSelectedLocales().iterator()
I find this more convenient than using a special-purpose getter and
setter to add to the list, as more of the code is in the .page (but it's
less type-safe).
Another approach might be to create a new component kind of like
Checkbox that wants two bindings: a key (IN), and a delegator that is a
Set to hold the selected values (OUT).

See the LocateList component at the Tapestry examples coming with the
Tapestry distribution. It is inside package org.apache.tapestry.workbech.table.
It has a example with checkboxes inside a table (but using inside a foreach
is very similar).

Which is pretty much what the ListEdit component does; it records a key for each iteration of the
loop as a hidden field; when form is submitted, the key is restored from the hidden field and used
to re-acquire the real object.

Hi,
I solve this problem by adding a hidden field next to checkbox component,
that store the unique identifier for particular row. Durring the form rewind
phase if the check box is cheked you could obtain the value from the hidden
field and process/do your use case with the value.

And that sounds to me like a Checkbox enclosed by a Foreach.

Hi all,
Let me describe in detail as to what I want.
I have html form, the elemnts of it(to be specific number of ChekBoxes )are
not known iitially.
I want the Checkbox to be populated as the runtime depending upon List that
is populated from the database.
i.e. If List.size()=2 i want 2 checkboxes to be populated
If List.size()=3 i want 3 checkboxes to be populated
and i would like to have values of respecive checkbox to be trapped in the
next page.
I hope this clears the scenario.

Seems like you could use the Conditional component for this:
<span jwcid="@Conditional" condition="ognl:isSomeCondition">
<!-- insert your checkbox here -->
</span>

Hi all,
Is it possible to add component(say CheckBox) at runtime.

I have a relevant question. I need to insert a Checkbox and a Form
component into a Table row (ITableColumnModel). I'm setting up the
ColumnModel in Java. Is it possible to do that?

No. The page layout must be, basically static. Remmeber that Tapestry applications use pools of
pages and may be distributed across a cluster ... if we were to allow the ability to add a component
to a particular instance of a page there's no effective way to coordinate that within the same JVM
or across the cluster.
However, Tapestry does a really good job using conditionals and loops within forms.
