I have a jsf page that has a <h:panelGroup> that appear according to an event triggered by <a4j:support>. This <h:panelGroup> appears at the end of the page, making it larger. I want to know how to hide this element and make the page turn back to the original state (without this extra space). Is there a ajax4jsf tag that do it for me?!
Hi people, I solved the problem using <h:panelGrid>!
