			depopulateManager(createSiblingMenuManager, createSiblingActions);

		Collection newChildDescriptors = null;
		Collection newSiblingDescriptors = null;
		ISelection selection = event.getSelection();
		if (selection instanceof IStructuredSelection
			&& ((IStructuredSelection) selection).size() == 1) {
			Object object = ((IStructuredSelection) selection)
				.getFirstElement();
			EditingDomain domain = ((IEditingDomainProvider) activeEditorPart)
				.getEditingDomain();
			newChildDescriptors = domain.getNewChildDescriptors(object, null);
			newSiblingDescriptors = domain.getNewChildDescriptors(null, object);
		}
		
		
		createChildActions = generateCreateChildActions(newChildDescriptors,
			selection);
		createSiblingActions = generateCreateSiblingActions(
			newSiblingDescriptors, selection);
		if (createChildMenuManager != null) {
			populateManager(createChildMenuManager, createChildActions, null);
			createChildMenuManager.update(true);
		}

			populateManager(createSiblingMenuManager, createSiblingActions,
				null);
