Hi,

there was a discussion about this problem 1 or 2 weeks ago. I can not
remember the name of the thread but somebody provided a simple solution
for it.

Hello varun,

You can see diff between 1.7 and 1.8 revisions of EcoreMatchingStrategy from
Ecore diagram example - this is the changes you have to introduce into your
generated diagramming code.

Hello varun,

- Open CVS and download Ecore diagram sample sources from there
- Open EcoreMatchingStrategy class - the class was re-generated with new
templates to correct the problem
- open CVS history for this class and see whan was changed from v1.7 to v1.8
- this is a fix for the problem. You should do the same in ???MatchingStrategy.

Hello varun,

> Does i have to make any other changes??
Try debugging your matching startegy. Idea of this class is to match two
different editors and if you areusing older verrsions of GMF then different
parameters could be passes to this method, but in general you should still
match them.

Now what i found is that on both the editor diagarm element of former

when i double click on the diagarm element of the editor a new editor gets
opened having diagarm element of later editor.

pls help me.

hi alex

i hv checked my ???matchingstrategy class after making the changes u told
earlier in matching strategy class.

what i am getting in matches(IEditorReference editorRef, IEditorInput
input)

here input is of type :- DiagramEditorInput whereas

editorInput = editorRef.getEditorInput();

this line return editor input as of type :- FileEditorInput.

so it doesnt enter into the loop :

if (editorInput instanceof URIEditorInput && input instanceof
URIEditorInput)
{
}
& always false is returned.

also this is what is written in my doexecutewithresult method in
opendiagram policy

protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
IAdaptable info) throws ExecutionException {
try {
Diagram diagram = getDiagramToOpen();
if (diagram == null) {
diagram = intializeNewDiagram();
}

final DiagramEditorInput editorInput = new DiagramEditorInput(
diagram);
IWorkbenchPage page = PlatformUI.getWorkbench()
.getActiveWorkbenchWindow().getActivePage();

page.openEditor(editorInput, getEditorID());
return CommandResult.newOKCommandResult();
} catch (Exception ex) {
throw new ExecutionException("Can't open diagram", ex);
}

thanks

Hello varun,

So, once more: you are using old version of GMF and in new version all these
problems are corrected.

If you still going to modify existing code manually then you have to implement
matches() method of the matching strategy to return "true" if
editorRef referencing editor openned upon the editorInput equals to the input
and "false" otherwise. That's it.
