Hi,
I was having problems with the MultiPageEditorPart and the Gef editors
that I embedded into the MultiPageEditorPart, specifically getting
selection changes. To fix this whenever I
MulitPageEditorPart#setActivePage() is called I set the selection provider
of the MultiPageEditor to be the GraphicalViewer of the newly selected
EditorPart. This all seems to work fine. So I was wondering if I'm
causing, or will cause problems by setting the selectionProvider? The
selectionProvider seems to be null before I set it and runs fine
afterwards. Any comments would be great.

i think you'd better to install a MultiPageSelectionProvider for a
MultiPageEditorPart in init() method.
consule the sample code bellow:
site.setSelectionProvider(new EditorMultiPageSelectionProvider(this));
and calss definition is:
EditorMultiPage is the MultiPageEditorPart name in my application
private static class EditorMultiPageSelectionProvider extends
MultiPageSelectionProvider {
private ISelection globalSelection;
/**
* @param multiPageEditor
*/
public EditorMultiPageSelectionProvider(EditorMultiPage editorMultiPage)
{
super(editorMultiPage);
}
public ISelection getSelection() {
IEditorPart activeEditor = ((EditorMultiPage) getMultiPageEditor())
.getActiveEditor();
if (activeEditor != null) {
ISelectionProvider selectionProvider = activeEditor.getSite()
.getSelectionProvider();
if (selectionProvider != null)
return selectionProvider.getSelection();
}
return globalSelection;
}
/*
* (non-Javadoc) Method declared on <code> ISelectionProvider </code> .
*/
public void setSelection(ISelection selection) {
IEditorPart activeEditor = ((EditorMultiPage) getMultiPageEditor())
.getActiveEditor();
if (activeEditor != null) {
ISelectionProvider selectionProvider = activeEditor.getSite()
.getSelectionProvider();
if (selectionProvider != null)
selectionProvider.setSelection(selection);
} else {
this.globalSelection = selection;
fireSelectionChanged(new SelectionChangedEvent(this,
globalSelection));
}
}
}

There already is a org.eclipse.ui.part.MultiPageSelectionProvider which
does this for you. If your multi-page editor extends MultiPageEditorPart
and you call the appropriate methods when adding new GraphicalEditors,
your problem should automagically be taken care of.
