Hey Dali,

try taking a look at this sample:
http://wiki.eclipse.org/STP/BPMN_Component/Samples#BPEL_to_B PMN_generation

It's quite advanced, but if you remove the SAX handling you should be fine.

Thanks,

Antoine

Yes, I think that the generated model uses a file for persistence.
However the file doesn't have to exist.

So if you use the default constructor for BPMNVisual2ProcessGenerator,
no file will be created.

Dali, if you look at the previous thread you will find your solution.

Encapsulate the diagram you created into a IEditorInput implementation
and set it on the editor.

Then override the setDocumentProvider method to set your own document
provider that will load the diagram without trying to open it as a file.

Thanks,

Antoine

Hi Antoine ,

i don't understand what you mean by "Encapsulate the diagram you created
into an IEditorInput" .

one more question : How can i pass a diagram to the setDocumentProvider to
be loaded , is it the result of the generateView Method of the Bpel2bpmn
generator ?

Best Regards,

Dali.

Object to then pass it to the document provider ?.
I mean after the generateView Call , how can i get the diagram ?

Hi antoine ,

i used the getGraphicalModel() form BpmnProcessgenerator to get the
diagram .

Now how can i encapsulate in an IEditorInput ??

Best Regards ,

Since you are in a particular case where you want to feed the editor
with your very own data, you have to implement your own IEditorInput, or
maybe you could reuse DiagramEditorInput
(org.eclipse.gmf.runtime.diagram.ui.parts.DiagramEditorInput ).

I hope it helps.

Yep. You can get the GMF sources and see that for yourself.
