Description Musharraf Hussain 2014-10-07 17:49:47 UTC 
Description of problem:
- jBPM6 allows BPMN2 processes which has no normal outgoing connection from Embedded Sub-Process. I have attached a simple BPMN2 process "org.jbpm.InvalidEmdeddedSubProcess.v1.0.bpmn2" which has an Embedded Sub-Process but the only outgoing connection coming out of that sub-process is coming through a boundary event attached to the sub-process. Shouldn't jBPM6 engine check for a normal outgoing connection from the sub-process as well?

Version-Release number of selected component (if applicable):
- BPMS 6.0.3
- jBPM 6

How reproducible:
- Always

Steps to Reproduce:
1. Import the attached "org.jbpm.InvalidEmdeddedSubProcess.v1.0.bpmn2" process into jBPM Web Designer and save it.
2. Validate it, and it does not give any error.
3. Execute it and it also does not give any error.

Actual results:
- The process validates and executes fine.

Expected results:
- The process should not be validated.

Additional info:
- NA

enhanced validation to throw exceptions in case embedded subprocess does not have incoming or outgoing sequence flows:
