hi, In eclipse when i create a Sub-process….I am not able to create bpmn.xml of the main diagram…every time it gives an error message saying "subprocess" has no diagram yet….even though there are diagram inside that subprocess… :!: . why this error error….
I fear there was no specific reason to leave the "older" option in there. Unfortunately, that means there are two code parts that perform the logic differently which is a bug as you pointed out, so that needs to be solved if it stays in. Thanks for testing and verifying this; I'll discuss internally what to do with the older variety.
I have verified the behavior you describe and it is indeed a bug in our code. I have created an issue to be resolved for the next release. You can track it here if you wish:
