I think it is.
The code you posted earlier is invoked whithin the run() method of an
Action. This action can be lauched with the context menu of a project. The
aim of that method is to merge all *.editor1 files into the model (and
later diagram) file and to visualize it as *.editor2_diagram.
In the electionChanged() method I fetch the URI of the project as follows:
IProject project = (IProject) structuredSelection.getFirstElement();
basePath = project.getLocationURI();
Then I try to set up the URI for the model and the diagram:
URI diagramURI = URI.createURI(basePath + "/pluginTest.gfme_diagram");
URI modelURI = URI.createURI(basePath + "/pluginTest.gfme");
I checked the coresponding folder and those files are being created...
Is it a problem that I'm trying to use the same project folder? Or does
getLocationURI() not return the URI needed (no error markers in my code)?
Thanks,
Marsha

Not a good idea. This is the physical location of the project. Use
URI.createPlatformResourceURI("/" + project.getName + "/...) to get a
logical URI that will reference the workspace properly..

Yes, it's not the URI you should be using...

Hi Ed,
Thanks a lot, that works perfectly. The method you recommend me to use is
deprecated however.
I saw that URI.createPlatformResourceURI(String pathName, boolean encode)
isn't. What does this boolean value effect?
Thank you,

Oops. :-) The boolean determines whether to encode characters that are
normally not used in a URI, like space. It's best to always use true
except in the rare case that you know the string is already encoded...

What do you mean by popup-menu for the diagram? Are you talking of the
context menu that appears when right-clicking into the diagram canvas or
on a diagram element directly?
> Have you accomplished this Marsha? (could you show me your solution if

Actually my popup menu extension is established with a object contribution
with the following object class org.eclipse.core.resources.IProject. But
if you explain me in more detail what you are trying to do maybe I can
help you...
Greets,
Marsha

Sorry, I can see now that I was quite unclear, comments below.

Yes. I've added an action to it that I want to launch a new editor/diagram.
> if you explain me in more

What I want is to right click an element an select to launch another
editor/diagram. I've accomplished to make such an action in the File
menu (with an IWorkbenchWindowActionDelegate). This works because the
action is located in that plugins ...part/ package.
Say we have plugin A and B. I want to launch editor B from an object in A.
I create a standard IObjectActionDelegate for the object in A. This
action is located in A's ...part/ package. When I call
"EditorDiagramEditorUtil.createDiagram..." in that action it creates an
A diagram (because it only have access to A's classes, not B's)
Thanks for helping,
Tomas Zijdemans

So if I get you right you have to plugins one XXX.a.diagram and the other
XXX.b.diagram. So you also have the corresponding ADiagramEditorUtil and
BDiagramEditorUtil classes in those plugins right? If you want to open a B
diagram you have to use BDiagramEditorUtil.createDiagram().
The context menu I'm using is established in a plugin apart from my editor
plugins. To be able to create the editor I have to add the specific editor
plugin into the plugin dependencies of the "context menu plugin". In your
case you should include the B editor plugin to the plugin dependencies to
be able to create such a diagram.
But I'm not sure if I got you right although...
Greets,
Marsha
