How to set onChange event handler for widgets defined inside union/group

[vi...@wipro.com]

Hi,

Can any one help me out..

How to define onChange event-handler for the widgets defined inside the
union?

What's wrong in the below code?

//flow script code

wid.lookupWidget('description_c').setValue('visible');

wid.lookupWidget('description_u/visible/description').onChange =
function (oldV, newV) {
    print("oldV::" + oldV);
    print("newV::" + newV);
};

//definition file

<fd:union id="description_u" case="description_c">
  <fd:widgets>
    <fd:struct id="visible">
      <fd:widgets>
        <fd:field id="description">
          <fd:datatype base="string" /> 
          <fd:selection-list> 
            <!-- TODO remove the below code   -->
            <fd:item value="1">
              <fd:label><i18n:text>test</i18n:text></fd:label>
            </fd:item>
            <fd:item value="2">
              <fd:label><i18n:text>test2</i18n:text></fd:label>
            </fd:item>
          </fd:selection-list>
        </fd:field>
      </fd:widgets> 
    </fd:struct>
    <fd:struct id="disabled">
      <fd:widgets></fd:widgets>
    </fd:struct>
    <fd:struct id="hidden">
      <fd:widgets></fd:widgets>
    </fd:struct>
  </fd:widgets>
</fd:union>
   

//template file

<ft:union id="description_u">
  <ft:case id="visible">
    <ft:struct id="visible">
      <!-- insert regular header row HTML stuff here -->
      <ft:widget id="description">
        <fi:styling submit-on-change="true" />
      </ft:widget>
    </ft:struct>
  </ft:case>
  <ft:case id="disabled">
    <ft:struct id="disabled">
      <!-- insert regular header row HTML stuff here -->
      <p>Please choose a Phone value first.</p>
    </ft:struct>
  </ft:case>
  <ft:case id="hidden">
     <p>hidden value</p>
  </ft:case>
</ft:union>
