Hi,
Im having a problem setting the state of a certain child of a repeater .
I have a simple repeater defined as:
...
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.
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.
