Hi Guys,

I am trying to check for null condition in transition but its not working for me. I have tried various possible ways of EL. I have tried following till now but nothing worked for me

<transition name="errorTrans" to="end">
 <condition>#{outputData == "null"}</condition>
 </transition>


 <transition name="errorTrans" to="end">
 <condition>#{outputData == null}</condition>
 </transition>

 <transition name="errorTrans" to="end">
 <condition>#{outputData is null}</condition>
 </transition>

 <transition name="errorTrans" to="end">
 <condition>#{empty outputData}</condition>
 </transition>
