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:
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:
1- copy and paste following code in $TOMCAT_HOME/webapps/alfresco/WEB-INF/classes/alfresco/extension/workflows/helloWorld.bpmn20.xml
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,

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.

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!

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."
