Bug 306738 Renderer does not synchronize ToolItem selection state with MToolItem
Build: I20100318-2100 I have an app with an MToolBar defining a set of tool items of type "radio". When I select a different tool item, the button states change. Upon quitting the application, however, the change of state is not written to the delta. As a result, when running the application again, the toolbar item states are not what they should be.

protected IEclipseContext appContext;
	protected E4Workbench wb;
	@Override
	protected void setUp() throws Exception {
		appContext = E4Application.createDefaultContext();
		appContext.set(E4Workbench.PRESENTATION_URI_ARG,
				PartRenderingEngine.engineURI);
	}
	@Override
	protected void tearDown() throws Exception {
		if (wb != null) {
			wb.close();
		}
		if (appContext instanceof IDisposable) {
			((IDisposable) appContext).dispose();
		}
