Workflow Decision Node

[tonyfoo]

Hi All,

I recently began creating an advanced workflow within Alfresco 3.1. At the moment the workflow is a pretty simple approval flow, however I am unable to get  a decision node to properly transition the flow in the right direction.

EX: The decision node should allow the token to the "Run Student Match" node only if the document is an xml document. Otherwise the flow should be sent towards the "Trigger Checklist Update" node. Please see my process definition below:

<process-definition  xmlns="urn:jbpm.org:jpdl-3.2"  name="scwf:recievetranscript">

   
   <swimlane name="initiator">
      <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
         <actor>#{bpm_assignee}</actor>
      </assignment>
   </swimlane>
   
   
   <start-state name="Assign Document Code">
      <task name="scwf:assignDocCode" swimlane="initiator"/>
      <transition to="Assign Code"></transition>
   </start-state>
   
   <node name="Assign Code">
   <event type="node-enter">
           <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
              
            <script>
               <variable name="bpm_package" access="read"/>
               <expression>
               logger.log("Transcript Process: Assign Document Code");
               if (!bpm_package.children[0].hasAspect("my:TranscriptFields"))
                  {
                        bpm_package.children[0].addAspect("my:TranscriptFields");
                  }
               bpm_package.children[0].properties["my:ID"] = "123456";
                  bpm_package.children[0].properties["my:RecievedDate"] = new Date();
                  bpm_package.children[0].properties["my:LastName"] = "xml";
                  bpm_package.children[0].save();
               </expression>
               </script>
                             
         </action> 
      </event> 
      <transition to="Is APAS Transcript?"></transition>

Any help would be greatly appreciated!
