bpm:assignee aspect not mandatory

coyoteugly — Mon, 20 May 2013 07:07:05 GMT

Hi, I'm performing some training tests on Alfresco advanced workflow using activiti. I'm able to create a simple workflow using use the bpm:assignee aspect. Anyway, to implement this I use the following code on my workflowModel-custom.xml :<mandatory-aspects> <aspect>bpm:assignee</a

Please share your process definition and workflow content model and let me know exactly you are trying to achieve.

This is only a low level fictitious example I'm trying to develop due to learn bpml and activiti from the base.
In my flow, after the User Task named "myTestUT1" I have an exclusive gateway. If the result of Exclusive gateway is "Approve", the flow choose the route to "myTestUT2" and the task is assigned to an user selected using the assegnee property in the previus Form. Anyway, if the the result of Exclusive gateway is "Reject", the flow proceed to "myTestUT3" assigned to a default user, so I do not need to use the assegnee aspect to choose the user.
There is a way to use the assegnee aspect as an optional aspect and not mandatory?

Thanks a lot, regards !

assignee is mandatory for a user task. I assume by default user you mean initiator, you can assign the user task to ${initiator.properties.userName}.

If it's not initiator then you can set the default user to a process variable and then assignee the user task to default user.

Hope this helps!!
