Removing workflow from system.

[andrisr]

Hi!
In a fresh Alfresco 3.2r instance I added an advanced workflow (which is used in another instance successfully).

Started up Alfresco and verified, that wokflow is available after selecting "Start Advanced Workflow" (there were two workflows, one of which was mine).
Without starting it, I shut down Alfresco and removed the workflow.
Then I started Alfresco again. Now, after selecting "Start Advanced Workflow",
I got an exception
 
  Namespace prefix rwsfr is not mapped to a namespace URI

and after that a message saying that there are no
workflows available. Prefix rwsfr is used by my workflow.
Adding a dummy model file with this prefix defined didn`t help.

I intend to try and change JBPMEngine.java to handle this situation.
But before that I wanted to ask whether there is something obvious, that I am missing?

Thanks!

Here is the exception.

How did you "remove the workflow"?      It will not be sufficient to just delete the workflow definition files.

Yes, all I did was removing workflow definition files.
What else would be necessary?
Is there something I have to remove from database?

Workflow administration console gives the same exception.

You could start deleting namespace entries in the database.  But that's not recommended.

Thanks
😕

For removing workflow from the alfresco u need to login with "admin" credential
then open page

http://localhost:8080/alfresco/faces/jsp/admin/workflow-console.jsp

now u can see all the workflow by executing command

show definitions all

and remove workflow by executing command

undeploy definition <workflow definition name>

try it
