Bug 312421 Contexts need to have a name

Object newWidget = createWidget(element, parent);
		
		if (newWidget != null) {
			AbstractPartRenderer renderer = getRendererFor(element);
			
			renderer.hookControllerLogic(element);
			
			
			if (element instanceof MElementContainer) {
				renderer.processContents((MElementContainer<MUIElement>) element);
			}
			
			renderer.postProcess(element);
			
			if (element.getParent() instanceof MUIElement) {
				MElementContainer<MUIElement> parentElement = element
						.getParent();
				AbstractPartRenderer parentRenderer = getRendererFor(parentElement);
				if (parentRenderer != null)
					parentRenderer.childRendered(parentElement, element);
			}
		} else {
			
			if (element instanceof MContext) {
				MContext ctxt = (MContext) element;
				IEclipseContext lclContext = ctxt.getContext();
				if (lclContext instanceof IDisposable) {
					((IDisposable) lclContext).dispose();
