a4j:repeat - Dynamically appending a new element

问题 I'm trying to implement (as part of a larger system) a feature where a user is able to post a message. When the user clicks the post button, I'm using RichFaces and a4j to retrieve the generated post using ajax. I'd rather not have the post show up automatically as soon as the response is returned. Rather, I'd like to add an output panel inside a hidden div. When the user clicks on the post button, that output panel will be populated but obviously hidden from the user. What I would like to do

Passing action in <rich:modalPanel>

facelets: passing bean name with ui:param to action attribute

由 老子叫甜甜 提交于 2019-12-19 04:21:52
问题 Due to some custom components which expect a bean name (NOT the bean instance) in their attributes I need to pass the actual bean name between pages. As the bean itself is also used by non-custom components, I would like to avoid using additional ui:param (like described here Passing action in <rich:modalPanel>) since it will essentially specify the same bean. Is it possible to specify component's action using bean name provided with ui:param ? Basically I am trying to achieve the following:

Using JSF AJAX methods to keep JavaScript module scope

由 梦想与她 提交于 2019-12-12 23:39:03
问题 I am working with the application, which has JSF2 framework. The idea of that framework is to manage connection between Backend (Java) and Frontend.

Inside several modules I need to make AJAX call to get some data from Backend, but if I am using standart

How can I achieve the requirement anyway? 回答1: Note: I'll ignore the careless formulation of the code which causes that it
