Question

基于以下链接How to programmatically add an AjaxBehavior to a UIComponent with primefaces中提出的解决方案我已经以编程方式实现了CommanLink。调用actionListener方法openDialogListener，但来自primefaces对话框架的openDialog不起作用。如果我将openDialogListener方法设置为普通的jsf命令链接，一切都按预期工作，所以我认为问题出在writeLink方法

这是我的代码：

private void writeLink(HtmlTag parent,String text) throws IOException{
    String action = "#{myBean.openDiaog}";

    CommandLink link = (CommandLink)FacesContext.getCurrentInstance().getApplication().createComponent(CommandLink.COMPONENT_TYPE);
    link.setId(FacesContext.getCurrentInstance().getViewRoot().createUniqueId());
    link.setValue(text);

    ExpressionFactory ef = FacesContext.getCurrentInstance().getApplication().getExpressionFactory();
    MethodExpression me = ef.createMethodExpression(FacesContext.getCurrentInstance().getELContext(), action, null, new Class<?>[]{BehaviorEvent.class});
    AjaxBehavior ajaxBehavior = (AjaxBehavior) FacesContext.getCurrentInstance().getApplication().createBehavior(AjaxBehavior.BEHAVIOR_ID);
    ajaxBehavior.setProcess("@this");
    //ajaxBehavior.setUpdate("@this");
    ajaxBehavior.addAjaxBehaviorListener(new AjaxBehaviorListenerImpl(me, me));
    link.addClientBehavior("click", ajaxBehavior);

    this.addChild(link);
    parent.getChildren().add(link);
  }

这里是听众

  public void openDialogListener(javax.faces.event.AjaxBehaviorEvent e){

    Map<String, Object> options = new HashMap<String, Object>();
    options.put("modal", true);
    options.put("draggable", true);
    options.put("resizable", true);
    options.put("width", 600);
    options.put("height", 500);          

    RequestContext.getCurrentInstance().openDialog("myDialog", options, null);
  }

不幸的是，没有错误/没有异常

以编程方式将AjaxBehavior添加到具有primeface
