Faulty step-through/pre-processing in the presence of multiple start events #351

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Open http://oryx-editor.org/backend/poem/model/2218/self
2. Start step-through
3. Only activity C is enabled

Desired behavior: Both A and C should be enabled

Possible problem:
BPMN pre-processing does not work properly

I can reproduce the described problem, but I don't think that it is a valid BPMN
model, see BPMN 1.1 spec:

{{{
If the Start Event is used, then there MUST NOT be other flow elements that do 
not
have incoming Sequence Flow — all other Flow Objects MUST be a target of at 
least one
Sequence Flow.
}}}

I propose to display a syntax error...
