Hi Andreas,

Something that might work is adding
extra (GEF) layers to the ProcessEditPart. You probably don't need (or
want) to modify the BPEL model. This could potentially all be done by using
GEF.

Currently there is no extension point
to plug anything else other than activities to the diagram but I can see
layers as one thing that people might want to extend. For now you might
be able to prototype by modifying the existing edit parts and in the future
we could discuss adding extension points to acommodate these use cases.

The first goal is to be able to draw up a behavioral interface for the
BPEL process, that is to simply add partners of the process to the view
and draw links between activities in the process and the partners.

It is not planned to actually edit the process model (in this first
step) but rather model this beh. interface externally and (in a second
step) make necessary changes to the process to support the intentions of
the process modeler.

So the first step is simply visual, drawing boxes (partners) and arrows
(links).

Regards,
Andreas
