I want to use the initial-size attribute of the repeater definition.
However I want to supply the value as form data and accessed as an

expressions in the form definition? For example, <fd:repeater
id=”objectListing” initial-size=”#{numberOfObjects}”>.
Yes, you can use it if your form definition is procuced by a pipeline
like this
<map:match pattern="myDynamicFormDefinition">
<map:generate type="jx" name="path to the form definition.xml"/>
</map:serialize type="xml"/>
</map:match>
After that you have to create your form using form = new
Form("cocoon:/myDynamicFormDefinition");
But I do not know how to give parameters to the form definition that
are not "map:parameter"s
Oh man, a dynamic form definition to set the initial size is definitely
overkill :-)
What about:
<fd:repeater id="objectListing">
<fd:on-create>
<fd:javascript>
var initialSize = ... whatever expression you want here ...
// Create new rows until we reach the wanted size
while(widget.size < initialSize) widget.addRow();
</fd:javascript>
</fd:on-create>
...
