Re: how to obtain selected values in a multi-value dropdown

Hi Robby,

Thanks for your email.  I wasn't able to get this to work...but was able 
to work around this problem as shown below.

       <fd:on-value-changed>
           <javascript>
               var value = event.source.getValue();
               var collection = new java.util.ArrayList();
                  for(var i=0; i&lt;value.length; i++) {
                    collection.add(value[i]);
                  }
         </javascript>
       </fd:on-value-changed>

Thanks again for your help.
Paul
