I have a bpmn model describing a process. I'd like to create another bpmn model which refers to that (external) process as a sub-process. What is the right way to do that? I am trying to load external resources to the container model and drag the imported resources to its diagram (when modeling in UML this works) but I can not actually do that from the BPMN 2 Modeler Outline

Hi Andrea,
In BPMN2 this is done with a Call Activity; a SubProcess refers to activities defined in the same physical file as the parent Process, Call Activities can refer to Processes defined in the same file or externally. To make an external Process visible, the file must be imported first (from the Imports list in the calling Process' Definitions property tab).
If you are targeting the jBPM runtime engine, there is no need to import the external Process file - simply enter the called Process' ID in the Call Activity's "Called Activity" property. The jBPM runtime will resolve IDs at runtime. If the called Process is not available, the engine will throw a runtime exception.

Hi Robert,
thanks for your kind help. I am trying to do what you suggested but I guess I am doing something wrong.
I am trying to add a reference to the improted model in the import section under the Definitions tab. However the only things it allows me to import are java types (not other bpmn models). Plus it takes a long time to interpret the URL I write and sometimes it crashes. Also I can not find in the CallActivity tabs in the diagram where to put the reference to an imported activity.
I instead managed to to that by means of the BPMN Model Editor where I managed to load the process to import as an external resource, I created a CallActivity and set its CalledElementRef property in order to point at the imported activity. Such things are however not reported (or at least I can't see where) in the digram.
I'd like to understand the right way to do that from the diagram

Hi Andrea,
I just had a long conversation with one of the developers on the jBPM team and it looks like the eclipse BPMN2 Modeler does not implement a CallActivity in the way that the jBPM engine expects. There are a few implementation details that are not being handled correctly - sorry for the confusion.
We should have this sorted out in the next service release, due sometime at the end of next month.
