I cannot start the standards WFs with the Alfresco Explorer, neither the Alfresco Share. I try the typical "assign task to colleague", when I try to finish it appear this error:
Please correct the errors below then click Finish.
A system error happened during the operation: 030723255 Failed to signal transition null from workflow task jbpm$2061.
I have not customized anything in the WFs.
Somebody can help me?
