How can I generate JSF UI components ASYNCHRONOUSLY on a jsf

[shiva.sk]

Hi Everybody,

I started reading into JBoss's RichFaces & Ajax4jsf which is now part of the later. I have the follwoing task to do :-

Scenario :
I have a menu with several links. When I click on one of the links, say for example 'Create New User' link, I have to get the page loaded ASYNCHRONOUSLY (i.e. through Ajax) with all the JSF UI components related to New User Creation and these components should be bound to the Managed Beans as usual.

Does anybody have sample code or links to any tutorials where in JSF input elements are generated ASYNCHRONOUSLY on a jsp/jsf page using Ajax4jsf?

Can we use it to generate all the JSF input elements (like h:inputText, h:inputTextArea, h:inputSecret, h:selectOneMenu, h:selectManyListbox, etc...) ASYNCHRONOUSLY?

Can anybody help me with resources related to this?

Regards,
Shiva

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"/>

Hi,

Sorry, since I am new to RichFaces & Ajax4jsf, I did not get what exactly your code does.

What I want to achieve is dynamic (i.e., ASYNCHRONOUSLY using Ajax req-res) form generation, with different JSF input elements (text box,combo box,list box,select many list box,command button, etc .) which are bound to Managed Bean on a jsf/jsp page when an user clicks on any link or button or just an user request for that matter.

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).

Hi Everybody,


Has anyone done this successfully till now ??

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.

Hi,

Could you provide working source code of your suggestion
