解决RCP中CNF（navigator）配置后delete/copy/past快捷键失效

这两天在配置一个CNF导航视图时候发现快捷键delete、past、copy等都失效了，折腾良久，搞清楚了；

1.快捷键要想能在菜单右边显示出来：

deleteAction.setActionDefinitionId(IWorkbenchCommandConstants.EDIT_DELETE);2.要想生效必须绑定handler：
@Override	public void fillActionBars(final IActionBars actionBars) {		if (textActionHandler == null) {			textActionHandler = new TextActionHandler(actionBars); // hook																	// handlers		}		textActionHandler.setCopyAction(copyAction);		textActionHandler.setPasteAction(pasteAction);		textActionHandler.setDeleteAction(deleteAction);		// renameAction.setTextActionHandler(textActionHandler);		updateActionBars();		textActionHandler.updateActionBars();	}
public void updateActionBars() {		actionBars.setGlobalActionHandler(ActionFactory.CUT.getId(),                textCutAction);		actionBars.setGlobalActionHandler(ActionFactory.COPY.getId(),                textCopyAction);actionBars.setGlobalActionHandler(ActionFactory.PASTE.getId(),                textPasteAction);		actionBars.setGlobalActionHandler(ActionFactory.SELECT_ALL.getId(),                textSelectAllAction);		actionBars.setGlobalActionHandler(ActionFactory.DELETE.getId(),                textDeleteAction);	}setGlobalActionHandler把id和action绑定到一块；
这里你发现绑定的action并不是自己那个action，是texthandler中的action；
如果想强制生效可以直接把这个action换成我们那个action；
3.推荐的解决方法：
之所以不生效，是因为系统找不到action对应的commandid，我们可以绑定：
PRotected void makeActions() {		clipboard = new Clipboard(shell.getDisplay());		...		deleteAction.setActionDefinitionId(IWorkbenchCommandConstants.EDIT_DELETE);		initActionCommandMappingService();	}	/**	 * 快捷键绑定actionBars.setGlobalActionHandler();	 * 这里使用了textActionHandler.updateActionBars();所以绑定的是textActionHandler中text*Action，而不是这里的action；	 * 方法一：重新设置setGlobalActionHandler为这里的action；	 * 方法二：ActionCommandMappingService中添加这里的action映射WorkbenchCommandConstants.EDIT_*	 */	private void initActionCommandMappingService() {		final IActionCommandMappingService actionCommandMappingService = (IActionCommandMappingService) CommonUIPlugin.getDefault().getWorkbench()				.getActiveWorkbenchWindow().getService(IActionCommandMappingService.class);		final String idDelete = actionCommandMappingService.getCommandId(ActionFactory.DELETE.getId());		if (idDelete == null) {			actionCommandMappingService.map(ActionFactory.DELETE.getId(), IWorkbenchCommandConstants.EDIT_DELETE);		}		final String idCopy = actionCommandMappingService.getCommandId(ActionFactory.COPY.getId());		if (idCopy == null) {			actionCommandMappingService.map(ActionFactory.COPY.getId(), IWorkbenchCommandConstants.EDIT_COPY);		}		final String idPast = actionCommandMappingService.getCommandId(ActionFactory.PASTE.getId());		if (idPast == null) {			actionCommandMappingService.map(ActionFactory.PASTE.getId(), IWorkbenchCommandConstants.EDIT_PASTE);		}	}这样问题就解决了
