Hi,
I created a collaboration diagram, and went to create a Choreography - only to observe that the objects from the Collaboration were not usable in the Choreography. What I found myself having to do is re-create the same objects (messages/etc), and place them on the Choreography diagram. For diagramming this is fine, yet I am certain I am creating a downstream problem, in that if I target an execution engine the redefinitions of objects will create a huge nightmare. My steps to create the Choreography were:
1) open Collaboration
2) use "Diagram" / "Create Choreography .."
3) select tab for the named Choreography under the bpmn2 for the Collaboration
4) create a "call activity", and use the participants from the collaboration, and try to like to an activity defined on the collaboration.
Leading me to my question...
It appears that Collaborations, Choreographies, and Process diagrams within a project are not connected (per the BPMN 2.0 SPEC Figure 8.3). I must be mistaken.
How does a modeler create a Choreography that uses the objects defined in the Collaboration?

Hi,
nope for the first question, and I'll kinda hold off answering the second.
I did some more research/analysis to see if I can figure out. What I know is I created three styles of BPMN files. Two where I created the file by using the "BPMN Model" wizard, and one where I created the bpmn file using "Diagram" wizard. All have different results when I open with the "Model Editor". In the three files, I redrew the Collaboration ( go figure, eh, but it was mostly cause I ran into problems so I would redraw the diagram to try and find out where). In all the two files were I used the "BPMN Model" wizard, the format seems to be incorrect. These two files show only a "BPMN Diagram" and while all the objects are available, there key difference is there isn't a diagram labelled "Collaboration" like in the bpmn where I started by using the "Diagram" wizard. The above four steps I did were with one of the bpmn files where I used the "Model" wizard. I suspect, the root of my problem is I used the "Model" wizard.
I went back to the spec - my problem was I wasn't creating the Choreography Call Task per spec. The messages are tied to the participant, where the Collaboration Call Task name aren't reused on the Choreography only the Collaboration messages. Wasn't related to the which the BPMN file creation wizard was used.
