jsf - Controlling component from backing bean -

i want 'update' component new component in bean.

xhtml

<composite:interface>   <composite:attribute name="rootkey"   required="true" />   <composite:attribute name="id"        required="true" /> </composite:interface> <composite:implementation>  <rich:panel id="#{cc.attrs.id}" binding="#{mybean.custompanel}"/>  <a4j:jsfunction name="createpanels"   action="#{mybean.createpanels}"   render="#{cc.attrs.id}">   <a4j:param name="rootid" assignto="#{mybean.rootid}"/>   <a4j:param name="rootkey" assignto="#{mybean.rootkey}"/> </a4j:jsfunction>  <script type="text/javascript"> /* <![cdata[ */   jquery(document).ready(function() {     createpanels('#{cc.attrs.id}','#{cc.attrs.rootkey}');   }); /*]]>  */ </script> </composite:implementation> </ui:composition> 

bean

private uipanel rootpanel;  public void setcustompanel(uipanel panel) {   rootpanel = panel; }  public uipanel getcustompanel() {   return rootpanel; }  public void createpanels() {   //try #1 : adding new panels children   rootpanel.getchildren().add((uipanel)createpanels(rootid,rootkey));   //try #2 : new panel component    rootpanel = (uipanel)createpanels(rootid,rootkey);    ...   rootpanel.setid(rootid); // id same 'placeholder' panelid    facescontext.getcurrentinstance().getpartialviewcontext().getrenderids().add(rootpanel.getid()); // rerender should done in xhtml js function. } 

with debugger see rootpanel changes new panel component, not in view. miss?

what try in short: generating dynamically components children panel component in xhtml view. generation needs 'rootkey' param generating right set.

using:

• jsf mojarra 2.1.19
• richfaces

the solution me rerender te parent, not actual component. adding new element children children bound component.

xhtml : added h:panelgroup around place holder.

<h:panelgroup id="#{cc.attrs.id}_parent">   <rich:panel id="#{cc.attrs.id}" binding="#{mybean.panel}"/>  </h:panelgroup>  <a4j:jsfunction name="createpanels"   action="#{mybean.createpanels}"   render="#{cc.attrs.id}_parent">   <a4j:param name="rootid" assignto="#{mybean.rootid}"/>   <a4j:param name="rootkey" assignto="#{mybean.rootkey}"/> </a4j:jsfunction> 

bean : try #1 right one.

public void createpanels() {   uipanel newpanel = (uipanel)createpanels(rootid,rootkey);   if(newpanel.getchildcount() >= 1){     rootpanel.getchildren().addall(newpanel.getchildren());     rootpanel.setstyleclass(newpanel.getstyleclass());     rootpanel.setheader(newpanel.getheader());   } }
