reRender binded panelGrid in serverside.

[xphree]

Hello,

I'm trying to reRender a panelGrid that binds to a server side component.

the ajaxCommandButton in serverSide reRenders the whole outputPanel, it works because the component h:outputText is reRendered but the panelGrid isn't reRendered.. if i refresh the page i see the changes but that is not the behaviour i expect.

Any idea ?

The Code:

<a4j:outputPanel id="sabanaGrid" ajaxRendered="true">
 <h:panelGrid binding="#{sabanaBean.sabanaGrid}">
 <f:facet name="header">
 <h:outputText value="Quieto #{sabanaBean.colu}" />
 </f:facet>
 </h:panelGrid>
 </a4j:outputPanel>
