Here's a simple problem for which I cannot seem to find a simple
solution (or any solution at all). I hope someone here can help me.
I have a Collection of Java beans. Each bean has a couple of properties:
"id" (Integer) and "name" (String).
I also have a form with a repeater:
<fd:repeater id="current">
<fd:widgets>
<fd:output name="id" id="id">
<fd:datatype base="integer"/>
</fd:output>
<fd:output id="name">
<fd:label>Name</fd:label>
<fd:datatype base="string"/>
</fd:output>
<fd:booleanfield id="select">
<fd:label>Select</fd:label>
</fd:booleanfield>
</fd:widgets>
</fd:repeater>
The repeater is bound to the collection:
<fb:repeater id="current" parent-path="." row-path="current">
<fb:identity>
<fb:value id="id" path="@id" direction="load"/>
</fb:identity>
<fb:on-bind>
<fb:value id="name" path="name" direction="load"/>
</fb:on-bind>
</fb:repeater>
As you can see, data is mostly read-only. I am just interested in the
value of the "select" field for selecting some rows to be further
processed.
I also created a template for displaying the repeater as a two-column
table. Column 1 is for the "select" widget, whereas column 2 shoud
display the "name" property. That was easy.
The next requirement is for each "name" to be a link to an URL which
depends on the value of the corresponding "id". Something like:
<ft:repeater-widget id="current">
<tr>
<td><ft:widget id="select"/></td>
<td>
<a href="/base/[INSERT-ID-HERE]"><ft:widget id="name"/></a>
</td>
</tr>
</ft:repeater-widget>
Now the question is: what would be the easiest way to put the "id"
property of the bean bound to the current row in place of the
"[INSERT-ID-HERE]" string?
You have to use the cforms macro library to get the id:
...
<jx:import uri="resource://org/apache/cocoon/forms/generation/jx-macros.xml"/>
...
<ft:repeater-widget id="current">
<tr>
<td><ft:widget id="select"/></td>
<td>
<a
href="/base/${repeater.getRow(repeaterLoop.index).lookupWidget('id').value">
<ft:widget id="name"/></a>
</td>
</tr>
</ft:repeater-widget>
