I'm using Alfresco Community 5.0d integrated with Siteminder SSO and ldap synchronization.
Whenever I try to create any kind of work flow I get the error dialog: "Workflow could not be started", "Workflow could not be started". There are no errors in the Alfresco or share logs.
If I log onto the Workflow Admin Console I see the definitions of the workflows that I tried to create. If I use one of these definitions and then execute start, I get the following error:
org.activiti.engine.ActivitiException: Unknown property used in expression: ${bpm_assignee.properties.userName}
and later …
org.activiti.engine.impl.javax.el.PropertyNotFoundException: Cannot resolve identifier 'bpm_assignee'
I have no idea what's wrong. I completely re-installed Alfresco, and still get the same error.
