This error occurs every time that my custom processes reaches the end event. For example i have made a hello world process composed of one start event, one service task and one end event:

<process id="helloWorld" name="Hello World">
    <startEvent id="startevent1" name="Start"></startEvent>
    <serviceTask id="servicetask1" name="Service Task" activiti:class="com.sample.workflow.executor.HelloWorldExecutor"></serviceTask>
    <endEvent id="endevent1" name="End"></endEvent>
    <sequenceFlow id="flow1" name="" sourceRef="startevent1" targetRef="servicetask1">
      <extensionElements>
        <activiti:executionListener event="take" class="org.alfresco.repo.workflow.activiti.listener.ScriptExecutionListener">
          <activiti:field name="script">
            <activiti:string>logger.info('Before service task');</activiti:string>
          </activiti:field>
        </activiti:executionListener>
      </extensionElements>
    </sequenceFlow>
    <sequenceFlow id="flow2" name="" sourceRef="servicetask1" targetRef="endevent1">
      <extensionElements>
        <activiti:executionListener event="take" class="org.alfresco.repo.workflow.activiti.listener.ScriptExecutionListener">
          <activiti:field name="script">
            <activiti:string>logger.info('After service task');</activiti:string>
          </activiti:field>
        </activiti:executionListener>
      </extensionElements>
    </sequenceFlow>
  </process>
in which the HelloWorldExecutor class is:

public class HelloWorldExecutor implements JavaDelegate {
   private Logger log;
   public HelloWorldExecutor() {
      log = Logger.getLogger(getClass());
   }
   @Override
   public void execute(DelegateExecution arg0) throws Exception {
      log.debug("Hello, World!");

   }
}
When i try to execute that process, by click "start advanced workflow" on a document in alfresco explorer, I see this output:

15:22:03,201 INFO  [org.alfresco.repo.jscript.ScriptLogger] Before service task
15:22:03,206 DEBUG [com.sample.workflow.executor.HelloWorldExecutor] Hello, World!
15:22:03,215 INFO  [org.alfresco.repo.jscript.ScriptLogger] After service task
15:22:03,289 ERROR [org.alfresco.web.ui.common.Utils] A system error happened during the operation: 05130004 Workflow path activiti$8205 does not exist.
org.alfresco.service.cmr.workflow.WorkflowException: 05130004 Workflow path activiti$8205 does not exist.
   …

What am I doing wrong? and what happened inside the process engine?

It seems that when a process reaches the end event, the process engine tries to continue the execution on a non-existent path.

Regards,
Francesco
