I am getting lots of exception mainly with cast exception while trying to add the GMF generated editor inside a multipageeditor .

Like Grid and Rulers stop working. Can anybody suggest me the solution.

Actually My problem is here -

Actually I am dumping the generated GMF Editor inside MultiPageEditor createPage method like this -

ShapesDiagramEditor editor = new ShapesDiagramEditor();
			int index = addPage(editor, getEditorInput());
			setPageText(index, "Design");

Well as soon as I do the above, the GMF autogenerated properties named Rulers and Grid shows ClassCastException as (as we click on the properties menus)

So this is the actual issue I am facing and I could not resolve the same
Along with this I am not able to set even the background color for editor, it won't reflect anything.
