a4j:poll não funciona

&lt;h:form id="tabelaDinamica"&gt;  
        &lt;a4j:region&gt;
			&lt;a4j:poll id="poll" interval="1000" enabled="#{readLogs.autoScroll}"
				action="#{readLogs.viewLog}" reRender="tabelaDinamica:poll,formLogs:textContentLog" /&gt;
		&lt;/a4j:region&gt;  
    &lt;/h:form&gt;
	&lt;h:form id="formLogs"&gt;
		&lt;div class="pagina"&gt;
			&lt;div id="header"&gt;&lt;/div&gt;
			&lt;div id="conteudo"&gt;
				&lt;h:panelGrid id="textContentLog" columns="1"&gt;
					&lt;h:column&gt;
						&lt;textarea id="jsftags:textArea" name="jsftags:textArea" cols="30" rows="5" wrap="off" class="textCont" readonly="readonly"&gt;
							&lt;h:outputText value="#{readLogs.contentLog}" rendered="#{!empty readLogs.contentLog}"/&gt;
						&lt;/textarea&gt;
						&lt;script type="text/javascript"&gt;
							document.getElementById('jsftags:textArea').scrollTop = 100000000;
						&lt;/script&gt;
					&lt;/h:column&gt;
				&lt;/h:panelGrid&gt;
      		&lt;/div&gt;
      		
			&lt;div id="menu"&gt;
				&lt;h:panelGrid columns="8" id="gridLog"&gt;
					........
&lt;h:selectBooleanCheckbox id="autoScroll" value="#{readLogs.autoScroll}" styleClass="checkBtn"&gt;
					       &lt;a4j:support id="enableAutoScroll" event="onclick" reRender="poll, autoScroll"/&gt;
					 &lt;/h:selectBooleanCheckbox&gt;
					&lt;h:outputLabel for="autoScroll" value="#{resources['label.autoscroll']}" /&gt;
				&lt;/h:panelGrid&gt;
			&lt;/div&gt;
			&lt;div id="footer"&gt;&lt;h:outputLabel value="#{resources['label.developmentcenter']}" /&gt;&lt;/div&gt;
			&lt;div id="version"&gt;&lt;h:outputLabel value="#{resources['label.version']}" /&gt;&lt;/div&gt;
		&lt;/div&gt;
	&lt;/h:form&gt;

Esta variavel readLogs.autoScroll é um boolean então eu queria que quando o h:selectBooleanCheckbox fosse ativado ele renderizasse o a4j:poll que e por sua vez ficasse chamando readLogs.viewLog() que atualiza a variavel readLogs.contentLog e renderizasse textContentLog e ao desabilitar fizesse o inverso...

Agradeço desde já a todos que poderem ajudar

Galera fiz outro teste... baseado no livro Practical RichFaces, Max Katz... mesmo assim não funcionou...

&lt;ui:composition xmlns="http://www.w3.org/1999/xhtml"
	xmlns:ui="http://java.sun.com/jsf/facelets"
	xmlns:h="http://java.sun.com/jsf/html"
	xmlns:f="http://java.sun.com/jsf/core"
	xmlns:a4j="http://richfaces.org/a4j"
	xmlns:rich="http://richfaces.org/rich"&gt;

	&lt;h:form&gt;
		&lt;a4j:poll id="poll" interval="500" enabled="#{clockBean.enabled}" reRender="clock" /&gt;
	&lt;/h:form&gt;
	&lt;h:form&gt;
		&lt;h:panelGrid columns="2"&gt;
			&lt;h:panelGrid columns="2"&gt;
				&lt;a4j:commandButton value="Start Clock" action="#{clockBean.startClock}" reRender="poll" /&gt;
				&lt;a4j:commandButton value="Stop Clock" action="#{clockBean.stopClock}" reRender="poll" /&gt;
			&lt;/h:panelGrid&gt;
			&lt;h:outputText id="clock" value="#{clockBean.now}" /&gt;
		&lt;/h:panelGrid&gt;
	&lt;/h:form&gt;
&lt;/ui:composition&gt;

e a bean

public class ClockBean {
private boolean enabled;
public ClockBean() {
}
public boolean isEnabled() {
return enabled;
}
public void setEnabled(boolean enabled) {
this.enabled = enabled;
}
public java.util.Date getNow() {
return new java.util.Date();
}
public String stopClock() {
enabled = false;
return null;
}
public String startClock() {
enabled = true;
return null;
}
}

ele só renderesa a primeira vez que eu click no start mas não repete mais nada....

por favor, Alguem ja usou isso?
