Hi all,
I want to execute an action inside a node and after continue with the workflow cilcle.
My node is this.

<node name="Controlla se il template PPT esiste">
      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <runas>admin</runas>
         <script>
            <variable name="templateExist" access="write"></variable>
            <variable name="alfrescoPathTriaTemplate" access="read"></variable>
            <variable name="companyhome" access="read"></variable>
            <expression>
               try {
                  logger.log("node [Controlla se il template PPT esiste], entrato con path ["+alfrescoPathTriaTemplate+"]");
                  var templateExist = companyhome.childByNamePath(alfrescoPathTriaTemplate);
                  var exist;
                  if (templateExist == null){
                     logger.log("node [Controlla se il template PPT esiste], NON ho trovato nessun template al percorso ["+alfrescoPathTriaTemplate+"]");
                     exist = false;
                  } else {
                     logger.log("node [Controlla se il template PPT esiste], ho trovato il template al percorso ["+alfrescoPathTriaTemplate+"]");
                     exist = true;
                  }
                  templateExist = exist;
                  executionContext.getToken().signal();
               } catch (e){
                  logger.log("transition [Decidi numero e nome progetto], error durante l'esecuzione dello script " + e);
               }
            </expression>
         </script>
      </action>
      <transition to="Il template esiste?"></transition>
   </node>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The problem is when I try to signal the node, I get this exception:

2010-12-16 18:13:16,931 INFO  [STDOUT] 18:13:16,931 User:enrico_z DEBUG [repo.jscript.ScriptLogger] transition [Decidi numero e nome progetto], error durante l'esecuzione dello script JavaException: org.jbpm.graph.def.DelegationException: org.jboss.soa.esb.services.jbpm.actionhandlers.EsbActionHandler cannot be cast to org.jbpm.graph.def.ActionHandler‍
