Is this an item that is actively being worked on by the product team ?
The lack of first order event support, message flows, choregraphies and colloborations makes it hard to fully model knowledge worker centric processes.
Have to resort to modeling workflows in another tool while modeling everything else in Provision.
With most BPMS platforms improving support for BPMN 2.0 the lack of BPMN 2.0 support for modeling work flows is seriously limiting IMHO.
