error opening the editor [message #619546]

Hi everybody ,

i'm trying to create diagram programmaticly from data that exists on
database.

i take this steps :

- extends the BPMNVisual2ProcessGenerator and then generate diagram
elements .
- Define my own editor provider (IDocument ) that loads the diagram in the
getDocument() Method.
- set my document provider in the setDocumentProvider() of the BpmnEditor.
- Trying to open editor with a basic editor input ( without any override)

i'm getting the following exception :

org.eclipse.jface.util.Assert$AssertionFailedException: null argument;

Dali, did you get the GMF sources as I recommended you do ?

The error comes from the fact that the object you pass to create the
root edit part is null.

The document should NOT be given to the document provider directly.
Instead it should be passed as an editor input, and your document
provider needs to extend AbstractDocumentProvider (since you don't use a
file) and implement the method createDocument(Object element).

That's where the magic happens.

Note that by no means I am a GMF expert, at least I am not familiar with
this part of the code. Looking up the code gave me the answers in 5
minutes. So make sure you have the source if that's not already the case.

Thanks,

Antoine

Hi Antoine ,

i'm following your advices but i still have two more questions :

1- How can i ensure that the diagram was created? ( i display the content
of the sem2NotationMap and it shows element is it enough ?)

2- What interface should implement my editor input ( i reused
DiagramEditorInput and it does not works)

Thanx a lot for help.

Best Regards,

Dali

The diagram is created when you create the generator instance.

What did not work ? Anything implementing IEditorInput and working for
you should work.
