Hi,i use jsFunction to rerender panel,but how to make rich:effect effective when a panel is rendered?
My code:

<a4j:form>
 <a4j:jsFunction name="showPanel" reRender="loginGroup">
 <a4j:actionparam name="p3" assignTo="#{page.loginPanel}"/>
 </a4j:jsFunction>
</a4j:form>


<a onclick="showPanel('yes')">show</a>


<rich:panel id="loginGroup" rendered="#{page.loginPanel=='yes'}">//default is "no"
....
</rich:panel>


<rich:effect name="effectShow" for="loginPanel" type="BlindDown" />

This code could rerender the panel,but how to use "effectShow()" fuction to enable rich:effect?
I've tried many ways,but all failed.
