How to unlock a jbpm token?

Hi,

I have an stalled workflow in a <decision> node, so I tried to signal the transition from the workflow console. But it can't be signalled because the token is locked (or at least it's wath I figured out due to logs).

Is any way to signal the transition?

Here the log :

org.alfresco.service.cmr.workflow.WorkflowException: Failed to signal

Hi,

Im trying to signal a WorkflowPath from an actionHandler but I'm getting

Caused by: org.jbpm.JbpmException: this token is locked by token[137]
   at org.jbpm.graph.exe.Token.signal(Token.java:185)
   at org.jbpm.graph.exe.Token.signal(Token.java:140)

Here is my handler class:

public class JustSignalItTaskActionHandler extends AbstractAlfrescoNodeActionHandler {

   @Override
   public void execute(ExecutionContext ctx) throws Exception {
                // initialize the current pats and tasks
      super.execute(ctx);
      for (WorkflowPath wfPath : this.currentPaths) {
         this.workflowService.signal(wfPath.id, null);
      }
   }

   @Override
   protected void initialiseHandler(BeanFactory factory) {
      this.workflowService = (WorkflowService) factory.getBean("WorkflowService");
   }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

and here is my node:

    <task-node name="task-node1" async="true">
      <event type="node-enter">
         <action class="de.ipeq.iqweb.business.workflow.handlers.JustSignalItTaskActionHandler" config-type="bean"></action>
      </event>
      <transition to="next step" name="go-forward"></transition>
   </task-node>
‍‍‍‍‍‍‍‍

Have someone some solution for the problem or some tips? Respectively a solution how can I automatically notify the token to proceed forward from a task-node?

Thanks and regards,
Angel
