Are you reRendering the modal panel when you display it? It exists on the page like any other component and all you are doing it making it display. <a:commandButton action="#{doSomething}" oncomplete="javascript:Richfaces.showModalPanel('msgDialog',{width:450, top:200})" reRender="errorMessages"/> | .. | .. | <rich:modaPanel id="msgDialog" ...etc | <s:div id="errorMessages"> | <h:messages/> | </s:div> | Cheers, Damian View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4080608#...
