Problem with a4j:keepAlive

[gustavodelgado]

Hello,

In some components that i need to dinamically change its properties, i use the binding to the same, so i set the propertie that i want on managed bean. But when use <a4j:keepAlive> to this managed bean, this operation stop to work, like the component didn't was rendered again. So the methods are normally executed.

I will post a simple sample:

<h:form>
 <a4j:keepAlive beanName="Login"/>

 <a4j:commandButton value="Mostra" action="#{Login.mostra}" ajaxSingle="true" reRender="grid1"/>
 <a4j:commandButton value="Oculta" action="#{Login.oculta}" ajaxSingle="true" reRender="grid1"/>

 <h:panelGrid id="grid1">
 <h:panelGrid id="grid2" binding="#{Login.grid2}">
 <h:outputText id="texto1" value="texto do grid"/>
 </h:panelGrid>
 </h:panelGrid>
</h:form>

I have 2 buttons and 2 methods to show or hidde "grid2". In managed bean I have:

 private HtmlPanelGrid grid2;

 public HtmlPanelGrid getGrid2() {
 return grid2;
 }

 public void setGrid2(HtmlPanelGrid grid2) {
 this.grid2 = grid2;
 }



 public void mostra(){
 grid2.setRendered(true);
 }

 public void oculta(){
 grid2.setRendered(false);
 }

If i remove the keepAlive, it works fine, else, the component is not refreshed on the page.

Thanks!
