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>
