Hello newsgroup,
I just installed the BPMN modeler. I programmatically made some
modifications (moved some tasks to a subprocess) to the underlying model
(the bpmn file) of a bpmn diagram. As I saw that I didn't get asked if
to reload the diagram because of some changes being made, I closed the
diagram file and re-opened it. But then I got some NPE's in the error
log and a strange diagram. Besides that I got the following error in the
log with the stacktrace below:

IRJS0007E Semantic refresh failed.

When I wnated to drag and drop elements on the canvas I got more NPE's.
Then I created a new model mirroring the same model which I expected
after my programmatically made modifications. Then I deleted the diagram
file and tried to invoke "initialize bpmn_diagram file" on the bpmn file
(normal behavior for GMF editors). The diagram was generated but when
opening it I got exactly the same errors as above. So I'm asking why is
that not supported or if I find a fix in the repository version?

best regards,
Jan

Not sure what you did or what you mean by programmatic changes.

I would tend to think you should not do this kind of thing. When modifying the semantic model, think about the diagram model too.

Thanks,

Antoine

Hi Antoine,

changes based on the EMF reflective API

but why? The diagram is only another presentation for the underlying
model. A textual representation is possible for a bpmn model, too.

Ok, that's the part of my programmatic changes. But why does it not work
to instantiate the diagram from the core bpmn file?

best regards,
Jan

It's possible that something is wrong with your semantic model. You should investigate that, note also that this is part of the GMF project, not the code of the BPMN modeler. That feature was never really reliable.

Thanks,

Hi Antoine,

> It's possible that something is wrong with your semantic model. You
What do you exactly mean with "semantic model"? I tell you how I tried
it out: First I started by creating a normal BPMN diagram. I have put my
tasks onto the canvas and drew the transitions. In parallel the bpmn
file, containing the underlying model, grows. After that, I deleted only
the bpmn_diagram file and right-clicked the bpmn file and invoked the
generation of the diagram. You see that the same model was created with
the diagram before. And after the creation I got the depicted errors and
exceptions.

> should investigate that, note also that this is part of the GMF project,

Should I discuss this in the GMF group? I've never had problems of
generating a diagram from a model with other metamodels. So I thought I
could find help directly from those guys who had created and extended
the graphical editor.

best regards,
Jan

Sure. We might have a bug opened for this as well.

Thanks,
