Hi, I know a4j and richfaces. I want to build a dynamic menu with rich:panelBar and <rich:panelBarItem. Every time a commandLink inside the panelBarItem is clicked only the desired content should be rerendert. My site is greated in classic style with header, menu on west-side and the center content. main.xhtml <div id="west"><ui:include src="./layout/navigation.xhtml" /></div> | | <div id="center"> | <h:panelGroup id="dritter"> | <ui:include src="#{pagecontent.mySite}" /> | </h:panelGroup> | </div> navigation.xhtml | <h:form> | <rich:panelBar height="300" id="panelbar" width="160"> | <rich:panelBarItem binding="#{pagecontent.myBarItem}" id="sf" label="Sonderfreigaben"> | <div><h:commandLink actionListener="#{pagecontent.find}" value="button"><a4j:support event="onclick" reRender="center"></a4j:support></h:commandLink></div> | </rich:panelBarItem> | </rich:panelBar> | </h:form> | from PageContentBean.java the find method | public void find(ActionEvent event){ | HtmlPanelBarItem modBarItem = (HtmlPanelBarItem)myBarItem; | ....... | mySite = "usereditor.xhtml"; | } After pressed button the usereditor page is display but the whole site is rerendert not only the center content. Is there a gap in my mind? Please, can someone tell me what is to do get this correctly working. An example would be helpful. I hope it was not to difficult to understand (non native speaker, sorry) Thanks Andi View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4029381#...
