Hi, what's the problem with just binding the value parameter of
http://tapestry.apache.org/tapestry4.1/components/form/checkbox.html ?
Well, the question becomes "what do I bind it to?". Up to now, I've been
using a static number of checkboxes per page, and each one has been
given an OGNL property as value, e.g.:
<input type="checkbox" jwcid="@Checkbox" value="ognl:someValue"/>
with the code having:
public abstract boolean getSomeValue();
In this case, I have a variable number of checkboxes per page, I'd need
to bind them to array elements (I guess) or some such. How do I do that
in OGNL?
As a simplified concrete example, I'd have something like this on the page:
<table>
<div jwcid="@For" source="ognl:itemList" value="ognl:currentListItem">
<tr>
<td><span jwcid="@Insert" value="ognl:currentListItem.name"/></td>
<td><input type="checkbox" jwcid="@Checkbox" value="???"/></td>
</tr>
</div>
</table>
What goes in "???" ?
Sorry if I'm missing something obvious here, but so far RTFM hasn't
clued me in sufficiently :/.

Hello all, using Tapestry 4.0.2 here (had some Javascript issues when
trying to upgrade to 4.1.x, so putting off upgrading till I figure those
out). Anyway, I'm now trying to implement a new functionality to our app
and am a bit puzzled as to the best way to do it.
What I want to do is have a list of items (0-N items), and a checkbox
next to each one (i.e. one checkbox per line item). Below this list I'll
have controls to "delete all checked items" (or in general, "do X to
checked items"). Pretty basic UI functionality... except that I'm
stumped as how to do it with Tapestry.
I'm generating the list with a normal @For loop, and that works fine.
The checkboxes I need some help on, though... how do I bind a list of
checkboxes to values, so that I can figure out which one is related to
which line item on form submit?
All help appreciated. If it requires upgrading to 4.1.x, then that's
doable too, with some extra work.
