repeater state and children

[Rashel Shehata <ra...@gmail.com>]

Hi,

Im having a problem setting the state of a certain child of a repeater .

I have a simple repeater defined as:

  <fd:repeater id="selection"  >
  <fd:widgets>

  <fd:field id="response" required="true" state="disabled">
          <fd:label>Response Label</fd:label>
          <fd:datatype base="string"/>
        </fd:field>
..other children
</fd:widgets>
  </fd:repeater>


Initially the response child is disabled but at some point i want to
activate all instances of the response child in the repeater

I have tried:
 widget.lookupWidget("../selection").getChild("response").state=
Packages.org.apache.cocoon.forms.formmodel.WidgetState.ACTIVE;

but i get an error:
TypeError: Cannot set property "state" of null

i get the same error using widget.lookupWidget
("../selection").lookupWidget("response").

However on trying the method, the response widget is activated for row 0(as
expected):
   widget.lookupWidget("../selection").getWidget(0,"response").state=
Packages.org.apache.cocoon.forms.formmodel.WidgetState.ACTIVE;

how do i activate all instances of the response widget in the repeater.
Thanks a miilion

You can just loop over all the rows in the repeater:

var repeater = widget.lookupWidget("../selection");
for(var i=0; i<repeater.getSize(); i++) {
     repeater.getWidget(i, "response").state = 
Packages.org.apache.cocoon.forms.formmodel.WidgetState.ACTIVE;
}

Of course the field wouldn't be enabled by default in any new rows 
added, so you'd need to write extra code to do so, probably an event 
handler on your add-row button.
