Alfresco don't start - Workflow problem

[rmiranda]

Hi,

Yesterday I had working in advanced workflow and today when I startup Alfresco Its don't start:

Console log:
…
Context initialization failed org.alfresco.error.AlfrescoRuntimeException: 02040000 Workflow deployment failed
…
Caused by: org.alfresco.service.namespace.NamespaceException: Namespace prefix rl is not mapped to a namespace URI

I know that its very probably be a problem with Workflow definition, but Alfresco don't start and I can't log me in Alfresco and fix this workflow.

¿Can I delete/fix my workflow if Alfresco don't start?

PD: Sorry my English.

Rodrigo.

As far as I know you cannot fix the problem if Alfresco doesn't start (unless you drop the database and start over).  I've had the same error before.  It happened when I deleted some process definitions.
If you deleted code, make sure you put it back.  And then sign in as Admin and go into the workflow console http://localhost:8080/alfresco/faces/jsp/admin/workflow-console.jsp and say: show definitions all.  Then choose the definition you want to delete and say: undeploy definition name jbpm$rl:yourprocess.
If you did not delete the workflow, just make sure you have everything mapped where it is supposed to go.
You have your processdefinition.xml, your model-context.xml, web-client-config-custom.xml, and your workflowModel.xml set up properly.

Hope this helps!
