Hello!

It's better to ask such kind of questions in a newsgroup. Fortunately
there was a similar question recently:

Subject: [gmf-dev] Creating copy of an existing diagram and model file

Dear gmf community,

please help me solving a little problem.

I try to open a pre-defined GMF-Diagram and to save this as a copy of it
to another diagram file.

My application under development is RCP-based.

*The unsolved problem*: the xyz.model_diagram contains "href"s to the
xyz.model file. And the copy of xyz still contains hrefs to the
original, template diagram.

Questions:
How do i reorganize all cross references within my gmf resource files
???
How is the model data copied from diagram X to diagram Y when copying
the content of X.model_diagram to Y.model_diagram?



Thx for any help!
Alex

Here the code snippet:

final Diagram diagramCopy = (Diagram)
EcoreUtil.copy(activeEditor.getDiagram());

final EObject modelCopy = EcoreUtil.copy()

ArrayList<IFile> affectedFiles = new ArrayList<IFile>();

AbstractTransactionalCommand copyCommand = new
AbstractTransactionalCommand(editingDomain, "CopyContent",
affectedFiles) {

  @Override
  protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
  IAdaptable info)throws ExecutionException {
    diagramCopy.setName(diagramUri.lastSegment());

    /* copy the content from the template to new editingDomain */
    newDiagramResource.getContents().add(diagramCopy);

   /* seems the model data is not copied from the diagram */

   /*PseudoCode*/
   openDiagram(newDiagramResource);

  // results in graphical copy of template but has reference to original
  template model. New model is empty.
