Kannan,
Have a look at how the gotoMarker method selects the object referenced
by a marker using setSelectionToViewer:
public void gotoMarker(IMarker marker)
{
try
{
if (marker.getType().equals(EValidator.MARKER))
{
String uriAttribute =
marker.getAttribute(EValidator.URI_ATTRIBUTE, null);
if (uriAttribute != null)
{
URI uri = URI.createURI(uriAttribute);
EObject eObject =
editingDomain.getResourceSet().getEObject(uri, true);
if (eObject != null)
{
setSelectionToViewer(Collections.singleton(editingDomain.get Wrapper(eObject)));
}
}
}
}
catch (CoreException exception)
{
LibraryEditorPlugin.INSTANCE.log(exception);
}
}
The other part of your question seems better for the GMF newsgroup.

Ed,
I called the setSelectionToViewer API, it opens the editor but the focus
is still not set on that element, my EditCommand looks like this,
EObject object; //the object on which the focus has to be set.
protected CommandResult doExecuteWithResult(IProgressMonitor
progressMonitor, IAdaptable info) throws ExecutionException {
IFile file = getEMFStudioFile();
StudioEditor studioEditor = (StudioEditor) provider.openEditor(new
FileEditorInput(file));
Object wrapper =
((AdapterFactoryEditingDomain)(studioEditor.getEditingDomain ())).getWrapper(object);
studioEditor.setSelectionToViewer( Collections.singleton(wrapper));
return CommandResult.newOKCommandResult();
}
Here am opening the EMF file in the editor, and am trying to focus on
the "object" which is member variable of Command. However
setSelectionToViewer doesnt seem to have intended effect. I tried to
debug through the code, which goes into jface methods like
updateSelection() etc, no error logs are generated or exceptions in
console. Am I missing something?
Is it some deferred effect like when i called provider.openEditor the
editor was already opened and setting selection wont have any effect on
the editor?

Kannan

Kannan,
It seems a little odd to do this as a command because commands are
typically undoable things put onto the command stack whereas this is
more of an action. I would imagine that the editor you open will have
a *copy *of the model in it and hence it can't select "object" because
there is a copy of "object" in that editor, rather than "object"
itself. You could use
studioEditor.getEditingDomain().getResourceSet().getEObject( EcoreUtil.getURI(object))
to find the copy.

It seems a little odd to do this as a command because commands are
typically undoable things put onto the command stack whereas this is
more of an action. I would imagine that the editor you open will have
a <b>copy </b>of the model in it and hence it can't select "object"
because there is a copy of "object" in that editor, rather than
"object" itself. You could use
