Description ksuzumur 2015-11-09 03:23:09 UTC 
Description of problem:
Multiple "None StartEvent"s should be validated by BPMN2 editor in JBDS.

BPMN 2 Diagram Editor can allow to input multiple None StartEvents. But the same bpmn file will be validated in the business-central with the following error.

unfortunately it is not fixed
get this error on Neon:

  BPMN2 Modeler - Diagram Editor	1.3.0.Final-v20160602-2145-B47	org.eclipse.bpmn2.modeler.feature.group	Eclipse.org
  BPMN2 Modeler - Examples	1.3.0.Final-v20160602-2145-B47	org.eclipse.bpmn2.modeler.examples.feature.group	Eclipse.org

As per BPMN2 definition a sub-process always starts with a None Start Event.

Comment 7 Jozef Marko 2016-08-16 06:57:47 UTC 
Hello Karl.

Thanks for your contribution. Just let me clarify two things.

1. Your problem is a little bit different form the original one. I suggest to file it into separate bugzilla and I suggest to attach source file of the process or at least similar/simplified process to keep your business private.

2. Red Hat bugzilla project serves for issues present in official tooling supported by Red Hat. You have problems with Modeler 1.3.0. Red Hat support for this version of modeler is still in the preparation phase. But never minds. You can file your issue into community eclipse bugzilla [1].
