JSF - Unhide jsf component when clicking another component

I'm trying to have a button that brings up an upload dialog. The way i'm trying to achieve this is similar to this: 

<h:outputText value="Click Me" id="testit">
  <a4j:support reRender="hideme" event="onclick" action="#{actions.switchTestRendered}"/>
</h:outputText>
<h:outputText id="hideme" value="back" rendered="#{actions.testRendered}"/>

With code in the backing bean:

private boolean testRendered = false;
public String switchTestRendered(){
 setTestRendered(!isTestRendered());
 System.out.println("Current Status:"+isTestRendered());
 return "success";
}

public void setTestRendered(boolean testRendered) {
  this.testRendered = testRendered;
}

public boolean isTestRendered() {
  return testRendered;
}

When I press the 'click me' label I can see that the switchTestRendered is run but the 'hideme' component does not reveal.

Any suggestions? Thanks!

From the code it can only be seen that after 'Click me' the 'hide' component renderer is not updating. You have to find out why

Got it. I should have reRendered the parent of the element which I'm trying to hide/show. In other words:

<a4j:support reRender="hideme" event="onclick" action="#{actions.switchTestRendered}"/>

should be:

<a4j:support reRender="father_of_hideme" event="onclick" action="#{actions.switchTestRendered}"/>

Thanks! Ben.
