You mean something like this?

<h:panelGroup id="newUserPanel">
 <h:panelGroup id="newUserContent rendered="#{backingBean.newUserSelected}>
 <h:inputText ...>
 </h:panelGroup>
</h:panelGroup>

<a4j:commandButton value="New User" action="#{backingBean.selectNewUser}" reRender="newUserPanel"/>

The button should run an action in your backing bean that sets the property mentioned in the "rendered" attribute of the content panel, and then reRender the newUserPanel (which will then include the newUserContentPanel since its' rendered attribute value has changed).

You should do some google searches for RichFaces documentation. IIRC the IBM site has some good and useful articles about it (and Facelets and JSF in general).

Also, just quit thinking its complicated. It really is as simple as using rich: and a4j: components rather than the MyFaces equivalents. And even if you can't do that, there is always a4j:support to add it to the MyFaces components.

Probably the hardest part at first is learning how to use a4j:region correctly (but if you stick the whole page in an a4j:region, your usually going to be ok, and any problems are easily solved by posting your questions here and showing your code).

you could add and remove components on the page dinamically using components binding. It doesn't matter if this ajax request or common post. So if you able to do this within pure JSF - then nothing difficult for you should appears.

The Ajax4JSF forums are closed, please move to the RichFaces Users forum: http://jboss.com/index.html?module=bb&op=viewtopic&p=4182856#4182856.

Thanks,
