Problema con timer en workflow

fstnboy · ‎19 Dec 2010

Buenas,

Estoy creando un workflow que publique los cambios de un sandbox de usuario a un servidor tipo TEST siempre que haya uno libre, en caso de que no haya ninguno liberado, se espera un tiempo y se vuelve a mirar si esta libre.


<state name="checkserveravailability">
      <timer name="repeaterTimer" duedate="10 seconds" transition="fire">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <script>
            logger.log("Executing the timer!");
               </script>
      </action>
      </timer>
      <transition name="fire" to="isserveravailable">
         <exception-handler>
         </exception-handler>
      </transition>
   </state>

    <decision name="isserveravailable">
       <event type="node-enter">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <script>
               logger.log("Checking server availability!");
                </script>
         </action>
         <action class="org.zaizi.alfresco.module.valueretail.villagewww.avm.wf.AVMCheckServerAvailability" />
      </event>
        <transition name="busy" to="checkserveravailability"/>
        <transition name="available" to="review">
           <cancel-timer name="repeaterTimer"/>
           <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <script>
               logger.log("Publishing the content to Prelive!");
               </script>
         </action>
         <exception-handler>
            <action class="org.alfresco.repo.avm.wf.AVMReleaseTestServerHandler"/>
         </exception-handler>
         <condition>#{wf_serverAvailable != null &amp;&amp; wf_serverAvailable == true}</condition>
        </transition>
   </decision>

El proceso lo hace bien, pero cuando esta a la espera y un servidor TEST se libera, el workflow parece que sigue su ejecucion. Pero, antes de terminar con la tarea siempre recibo el siguiente error y el workflow se queda estancado ya que no hay timer.

Alguna idea del porque o de como solucionarlo??

Gracias!

Alguna idea de alguien? Nadie ha tenido este problema?

Para el que le interese:

el problema era que en la tarea "review" usaba una clase que publicaba los cambios en el servidor tipo TEST disponible. Dicha clase usaba el workflow service para recuperar el contenido del paquete del workflow. Por alguna razon parece que existen problemas al usar el workflow service en una clase Java y con Timers.. Mismo problema en este hilo del foro ingles
