[checco]

Hi,
Does anyone can explain me following error?

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

Ok,
I think that is a bug, because if i substitute the serviceTask with a userTask everything works fine.

Maybe the same thread that start the process cannot end the process?

Before I report the problem on https://issues.alfresco.com I wonder if this problem also occurs to some of you.

If you want to reproduce the problem with little effort follow this step:

3- download the helloWorld-wf.jar from http://dl.dropbox.com/u/16989192/helloWorld-wf.jar and copy it in $TOMCAT_HOME/webapps/alfresco/WEB-INF/lib/
4- start alfresco
5- navigate to any document and click the "start advanced workflow"
6- select the Hello World process and then click next/finish buttons until you've got the error described in previous post

Waiting for a response,
Francesco

By the way,
I use a workaround for this problem: on every path of the workflows that can directly reachs any endEvent from the startEvent without suspend the execution i have put a timerCatchEvent with a period of 5 seconds!

In this way the thread that execute the process change and no exception is thrown!

Hi there,

I can reproduce this behaviour and I think it's a bug, so did anyone raise a JIRA-issue already?

Kind regards,

[tonyrivet]

I know this is a very old issue but I think the problem still exists : an error is thrown when the workflow reaches the end event from the start event without going through any user task.

Is it a known issue ? Was a JIRA raised (couldn't found any) ?
Thanks.

[voula_11]

I had a similar issue in 5.0.d.
I fixed it by ending the workflow with a "TerminateEndEvent". It isn't documented in the Activiti User Guide but it works!

[atifsiddiqui]

Is this issue fixed?
I am facing the same issue and tried the workarounds of terminatedendevent but it didn't seems to work, Also my workflow has 5 user tasks before it terminates.
The moment I click on the Start Workflow I am getting the exception "Workflow path activiti$1642 does not exist."
