Transition cond. not working with variable in action class

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hi,
We have encountered some problem when we declare a variable in the script,when we are using action class in the decision node.Below  exception raised when we perform the transition.
We tried using variable declaration without using action class. Here, the transition worked fine. But, if we assign a value to the variable from action class, the transition condition is not working and always executes the first transition. Here no exception raised.

Kindly provide the solution for using variable in action class and with transition condition.

<decision name="isApproved">              
   <event type="node-enter"> 
        <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript"> 
              <script> 
        <[b]variable[/b] name="wfl_checkStatus" access="read, write"/>
             <expression>                       
      wfl_checkStatus  = bpm_package.children[0].properties["ck:Status"];               logger.log("Status "+wfl_checkStatus);                   
                       </expression>
                </script> 
             </action>
      </event>   
        <transition name="approve" to="published" >          
          <condition>#{wfl_checkStatus == "Waiting for Validation"}</condition>
        </transition>
        
        <transition name="Re-edit" to="editing" >
           <condition>#{wfl_checkStatus != "Waiting for Validation"}</condition> 
        </transition>
</decision>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I am not sure if you have already found the solution, but this might be helpful for others. Try this:

    <decision name="isApproved">            
       <event type="node-enter">
            <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
                  <script>
            <variable name="wfl_checkStatus" access="read, write"/>
            <variable name="bpm_package" access="read"/>
                 <expression>                      
          wfl_checkStatus  = bpm_package.children[0].properties["cktatus"];               logger.log("Status "+wfl_checkStatus);                 
                           </expression>
                    </script>
                 </action>
          </event>  
            <transition name="approve" to="published" >         
              <condition>#{wfl_checkStatus == "Waiting for Validation"}</condition>
            </transition>
          
            <transition name="Re-edit" to="editing" >
               <condition>#{wfl_checkStatus != "Waiting for Validation"}</condition>
            </transition>
    </decision>
