Hello All,

Iam new to Alfresco and I am looking into the workflow option. I downloaded the source (publish whitepaper sample) and pdf Alfresco Developer: Advanced Workflows from Jeff Potts. When I deploy the sample I get the error
"11:40:02,406 ERROR [org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/alfresco].[JBPMDeployProcessServlet]] Servlet.service() for servlet JBPMDeployProcessServlet threw exception
org.alfresco.service.namespace.NamespaceException: Namespace prefix scwf is not mapped to a namespace URI".

So I removed the scwf prefix in the processDefinition.xml and it got deployed. In Alfresco I also get the publish whitepaper as an Advanced Workflow Option.
But when I press next next and go to finish I get the folling error "A system error happened during the operation: Failed to signal transition 'null' from workflow task 'jbpm$11'"

Does anyone have a clue what I might have done wrong?
