		addGotoMenu(menu, element, size);
		
		addOpenNewWindowAction(menu, element);
		
		super.fillContextMenu(menu);

		boolean enabled= size == 1 && fPart.getViewer().isExpandable(element) && (isGoIntoTarget(element) || element instanceof IContainer);
		fZoomInAction.setEnabled(enabled);
		if (enabled)
			menu.appendToGroup(IContextMenuConstants.GROUP_GOTO, fZoomInAction);
