Hi,

due to BPMN 2.0 specs (p. 180, also Figure 10.36), adhoc subprocesses can have standalone activities with no flow. However, in the modeller this produces an "no outgoing connections" error.

Thanks

I created a patch to fix this.

However, i'm not completely sure about this, since it allows flow sequences like: StartEvent->Task (no EndEvent), which might also be seen as forbidden for ad-hoc processes.

Maybe the validator should implement a check like: If there is a start or end event, there has to be a valid flow between them. What do you think? The spec is not very clear about this.

However, even without this fix, there are questionable processes declared as "valid".

Hi again Tobias,

Thanks for the patch! It would really help a lot if you could create a bugzilla and attach the patch code, so it can be tracked (also, it will help others in the community who may have come across this same issue).

Validation in the editor is still an area that needs some work, and it's on the to-do list. If you'd like to contribute in this area, please let me know and I'll be happy to help you get started Smile

Cheers,
Bob
