Hi Simone
Thanks for this...
The reason I asked this question is that we were trying this exact approach
(though not using a union), but since we are using Ajax, we have been
getting an error...
This is part of the definition for the form in question
It works correctly when we don't use Ajax, however
using Ajax we get the javascript alert error message:
"No element "life2" defined in document" after the item is selected.
(If kwdJointSingle is set to Single then only Life1 is enabled, otherwise
Life2 is also enabled)
Any ideas?
<fd:field id="kwdSingleJoint">
<fd:label>Is this policy a Single Life or Joint Life
policy?</fd:label>
<fd:datatype base="string"/>
<fd:initial-value>Single</fd:initial-value>
<fd:selection-list>
<fd:item value="Single"/>
<fd:item value="Joint"/>
</fd:selection-list>
<fd:on-value-changed>
<javascript>
var value = event.source.value;
var dob1Starwidget =
event.source.lookupWidget("../life1/dob1Star");
dob1Starwidget.setValue(" * ");
var life2widget =
event.source.lookupWidget("../life2");
var title2widget =
event.source.lookupWidget("../life2/title2");
var firstName2widget =
event.source.lookupWidget("../life2/firstName2");
var lastName2widget =
event.source.lookupWidget("../life2/lastName2");
var gender2widget =
event.source.lookupWidget("../life2/gender2");
var gender2Starwidget =
event.source.lookupWidget("../life2/gender2Star");
gender2Starwidget.setValue(" * ");
var dob2widget =
event.source.lookupWidget("../life2/dob2");
var dob2Starwidget =
event.source.lookupWidget("../life2/dob2Star");
dob2Starwidget.setValue(" * ");
if (value == "Joint")
{
life2widget.setState(Packages.org.apache.cocoon.forms.formmodel.WidgetState.ACTIVE);
gender2Starwidget.setState(Packages.org.apache.cocoon.forms.formmodel.WidgetState.ACTIVE);
dob2Starwidget.setState(Packages.org.apache.cocoon.forms.formmodel.WidgetState.ACTIVE);
}
else
{
life2widget.setState(Packages.org.apache.cocoon.forms.formmodel.WidgetState.DISABLED);
title2widget.setValue(null);
firstName2widget.setValue(null);
lastName2widget.setValue(null);
gender2widget.setValue(null);
gender2Starwidget.setState(Packages.org.apache.cocoon.forms.formmodel.WidgetState.INVISIBLE);
dob2widget.setValue(null);
dob2Starwidget.setState(Packages.org.apache.cocoon.forms.formmodel.WidgetState.INVISIBLE);
}
</javascript>
</fd:on-value-changed>
