Hi dudes, I'm working on JSF,Hibernate,& Spring in my project. I'm loading data for my JSF through my backing bean. When using ajax in my JSF, I don't get what is the use of this a4j:region and what is the difference between h:commandButton and link and a4j:commandbutton and link. Also when i want to pass parameters to my backingbean which will be better a4j:parameter or h:paramname Come dudes I'm waiting for your reply.
The a4j tags are for AJAX-enabled RichFaces support. An a4j:region is simply a block of page source that can be made the target of an AJAX operation such as partial page refresh. Except for the AJAX, it's a lot like the HTML <span> tag.
Likewise the aj4 command and link tags are like their core JSF equivalents, except that they provide attributes that permit them to be used to perform AJAX operations.
