JBoss Richfaces ModalPanel - condition based invokation

I am using JBoss Richfaces and I need to invoke rich:modalPanel when a particular condition happens.

The sample code is here--

This is the modalpanel

<rich:modalPanel  id="show_alert" height="125" width="325" zindex="2000">
       <h:outputText value="shamik testing"/><br/>
       <a4j:commandButton value="#{uiLabel.no}" onclick="#    {rich:component('show_alert')}.hide()" styleClass="button"/>
</rich:modalPanel>

I want to show the modal panel when someone clicks this link.

<a4j:commandLink value="#{uiLabel.config_ret}" id = "aaa"

actionListener="#{aging.configureRetention}"          reRender="cp_tab_form">
<rich:componentControl for="show_alert" attachTo="aaa" operation="show" event="onclick"/>     
</a4j:commandLink>

I am trying to make operation="#{bean.cond}" so that the name of the operation comes dynamically. But does not working.

I want to call operation = hide when bean.cond = false and operation = show when bean.cond = true.

I might be doing something very stupid here :-(

From stackoverflow

• Sorry for posting it.. I was not rerendering the commandLink :-( sorry for it.

• You could also look at using the "data" attribute of the a4j:commandLink to return the value of the bean.cond

• This is possible using the tag.
