Activiti, Alfresco, TimerStartEvent and Initiator

[bprado]

[posted on Alfresco forums but got no answer: http://forums.alfresco.com/forum/developer-discussions/workflow/timerstartevent-how-set-initiator-03... ]

Hi all,

I'm new to Alfresco and Activiti and after some digging was finally able to create, deploy and redeploy advanced custom workflows created with Activiti designer plug in for eclipse.
Unfortunately I had problems working with "TimerStartEvent". The TimerEventDefiniton worked as expected, and all my workflows were created "on time". My workflow, however, had incomplete properties, and "initiator" was missing. As a consequence, the tasks won't show in MyTasks (error in JavaScript) and tasks cannot be ended (error in log).
From what I could figure, If I could set the initiator of the workflow, everything would work as expected. Please notice that I tried setting activiti:initiator on StartEvent without success.

Any advice would be appreciated.

Alfresco version is 4.2.b (since 4.2.c is giving me errors when using custom workflows)

No, the execution-listeners run inside the process, so no matter how the process is started (worklfowService API, rest-call, timer-start, ..) this will be called.

I am having the same problem. I am starting workflow instances, or should be, to different users with javascript. Can not get the Initiator attribute to a chosen user. It's always the user who runs the script/JS.

How would I use a javadelegate and a service task?
