reRender on a4j:commandButton only works once
---------------------------------------------

                 Key: RF-4440
                 URL: https://jira.jboss.org/jira/browse/RF-4440
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.2.1
         Environment: Netbeans 6.1; Sun Java Application Server 9.1 under Windows XP Professional 32-bit. Tested with Chrome and IE8.
            Reporter: Stefan Mohr

Sample code to reproduce:

JSP:
--------
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://richfaces.org/rich"prefix="rich" %>
<%@ taglib uri="http://richfaces.org/a4j" prefix="a4j" %>

<html>
  <body>
    <f:view>
      <a4j:form id="pnlMain">
	  <a4j:commandButton action="#{TestBean.goView2}" rendered="#{TestBean.drawView1}" value="Go"            reRender="pnlMain" />
	  <a4j:commandButton action="#{TestBean.goView1}" rendered="#{TestBean.drawView2}" value="Back to table (Broken)" reRender="pnlMain" />
	  <h:commandButton action="#{TestBean.goView1}" rendered="#{TestBean.drawView2}" value="Back to table (Working)">
	    <a4j:support reRender="pnlMain" />
	  </h:commandButton>
      </a4j:form>
    </f:view>
  </body>
</html>
-------

Backing Bean:
-------
package test;

public class TestBean
{
  private int currentView = 1;

  public TestBean()
  {
  }

  public boolean getDrawView1()
  {
    return currentView == 1;
  }

  public boolean getDrawView2()
  {
    return currentView == 2;
  }

  public String goView1()
  {
    currentView = 1;
    return null;
  }

  public String goView2()
  {
    currentView = 2;
    return null;
  }
}
-------

To test:
Deploy page and click first "Go" link - page rerenders.
Now click "Back to table (Broken)" - page won't rerender.
The "(Working)" link, which uses a4j:support on an h:commandButton, works as expected.
