I wanna have a global scoped variable that all tasks can access either inside javascript or beanshell script. I have this code and I get null for requiredApprovePercent variable:

Start task with defined variable: requiredApprovePercent

<start-state name="start">
  <task name="agfo:submitForReviewTask3">
   <event type="task-end">
    <script>
     <variable name="task_comment" access="read,write"/>
     <variable name="task_id" access="read,write"/>
     <variable name="requiredApprovePercent" access="read,write"/>
     <expression>
      if(taskInstance.comments.get(0).message != null) task_comment = taskInstance.comments.get(0).message;
      if(taskInstance.id != null) task_id = taskInstance.id;  
     </expression>
    </script>
   </event>
  </task>
  <event type="node-leave">
   <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
    <script>
     …
     var configNodeRef = bpm_package.children[0].properties["aginv:ChosenConfigNodeRef"];
     var config = search.findNode(configNodeRef);
     requiredApprovePercent = config.properties["agfo:wfRequiredApprovalPercent"];
     …
    </script>
   </action>
  </event>
  <transition to="fork"/>
 </start-state>

Decision node where I want to access that variable:

<decision name="reviewDecision">
  <event type="node-enter">
   <script>
    <expression>
     …
     System.out.println("requiredApprovePercent= " + requiredApprovePercent);
     …
    </expression>
   </script>
  </event>
  <transition to="a">
   <condition>#{………….}</condition>
  </transition>
  <transition to="b"/>
 </decision>

You need to read the JBPM documentation with respect to the mapping between "process variables" and "task variables".

In alfresco we tend to define an aspect that contains all the "global variables", look at the existing workflows for examples.
