Hello all,

I want to determin the Agent(s) for the following task  in dependence of some points outside the workflow. I would use a methode of my  workflow class, and I need to know  which workflow container element I need to fill , and which Task container element .

And how can I tell the workflow, the agent assignment is dynamically.

Could any body help me
