org.jbpm.graph.def.DelegationException: A valid SecureCon...

A task is assigned to a pool and declares a timer which in turn contains a JavaScript Action. When the timer fires before somebody claims ownership of the task, timer execution fails with the following exception (quoted from Alfresco's database, column jbpm_job.EXCEPTION_)

How can I execute a timer attached to a task even if the task is not assigned yet? A delay in task assignment is one of the things that timer is supposed to handle …

Hi,

I'm facing a similar problem. A timer fires and moves to the decision node, which is then supposed to start an action. I get the following exception:

This does not happen when the timer node is ommitted and the previous node leaves directly to the decision node. Below is the process definition:

   <state name="timerState">
      <timer duedate="1 minute" transition="fire"/>
      <transition name="fire" to="checkTime"></transition>
   </state>
   <decision name="checkTime">
      <event type="node-enter">
      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <runas>admin</runas>
         <script>
               <expression>
                  var act = actions.create("TimerActionBean");
                  for (var i = 0; i &lt; bpm_package.children.length; i++) {
                     act.execute(bpm_package.children[i]);
                  }
                  testwf_ret_val = act.parameters["timer_due"];
               </expression>
               <variable name="testwf_ret_val" access="read,write" />
               <variable name="bpm_package" access="read" />
         </script>
      </action>
      </event>
      <transition to="nextWorkflowNode" name="timerFired">
         <condition>#{testwf_ret_val == "true"} </condition>
      </transition>
      <transition to="timerState" name="to timerState">
         <condition>#{testwf_ret_val == "false"} </condition>
      </transition>
   </decision>

If this post is unanswered because it's a duplicate, I would very much appreciate to be pointed to the correct thread as I have not been able to find it myself.

Thx in advance,
