您可以在JSF Renderer中添加子组件吗？

Question

I would like to add a child component while inside of the encodeBegin

 public void encodeBegin(FacesContext context,
   UIComponent component)
   throws IOException {
    XspInputText xip = new XspInputText();

  ViewPickList vplComponent = (ViewPickList) component;
  ResponseWriter writer = context.getResponseWriter();
  String viewName = vplComponent.getViewName();
  if (StringUtil.isNotEmpty(viewName)) {
          xip.setId(vplComponent.getId() + "_InputText");
   xip.setValue("Value");
   vplComponent.getChildren().add(xip);
  super.encodeBegin(context, vplComponent); 


  }

This doesn't appear to work, but I am trying to add the child component inside and have it render. Can anyone suggest a better way of doing this?

Answer 1

You should call you newly added components encodeBegin and encodeEnd methods to render them too.

Try this:

  xip.encodeBegin(context);
  xip.encodeEnd(context);

Please give me feed back if it works or not!
