I have an Alfresco Community edition, version 5.2, with a custom workflow implemented. This is the scenario:
a user loads a document into the platform and choose another user to be the document's author. Then he starts this workflow with the custom logic, as if the document's author would have started it.
I achieved this reassigning the workflow initiator with an execution listener, just after the start ScriptExecutionListener, but I got this error message popop, nothing is logged to console or browser.
