i try to integrate a page via a4j:include. but when i do that the a4j:commandbutton doesn't work any more.

first the page is

<?xml version="1.0" encoding="ISO-8859-1"?>
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
 xmlns:s="http://jboss.com/products/seam/taglib"

 xmlns:a4j="http://richfaces.org/a4j">
<a4j:form>
 <h:outputLabel value="Funktionsstatistik" style="font-size:21px" />
 <br/>
 <a4j:log level="ALL" popup="false" />
 <a4j:commandButton action="#{Profiler.clear}" status="globalStatus" bypassUpdates="true" immediate="true" value="Zurücksetzen" reRender="profiletable,counter" ></a4j:commandButton>
 <a4j:region id="profileregion">
 <h:outputText value="#{Profiler.count}" id="counter" />
 <rich:extendedDataTable value="#{Profiler.profiledata}" var="data" id="profiletable"
 onRowMouseOver="this.style.backgroundColor='#FFFF99'" rows="0"
 onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"
 cellpadding="0" cellspacing="0"
 width="100%" border="0">

 <rich:column sortBy="#{data.name}" style="text-align:left;" label="Name" width="200px" >
 <f:facet name="header" >
 <h:outputText value="Funktion" />
 </f:facet>
 <h:outputText value="#{data.name}" />
 </rich:column>
 <rich:column sortBy="#{data.count}" style="text-align:left;" label="Anzahl" >
 <f:facet name="header" >
 <h:outputText value="Anzahl" />
 </f:facet>
 <h:outputText value="#{data.count}" />
 </rich:column>
 <rich:column sortBy="#{data.avg}" style="text-align:left;" label="Durchschnitt" >
 <f:facet name="header" >
 <h:outputText value="Durchschnitt" />

 </f:facet>
 <h:outputText value="#{data.avg}" >
 <f:convertNumber minFractionDigits="3"/>
 </h:outputText>

 </rich:column>

 <rich:column sortBy="#{data.min}" style="text-align:left;" label="Minimum" >
 <f:facet name="header" >
 <h:outputText value="Minimum" />
 </f:facet>
 <h:outputText value="#{data.min}" >
 <f:convertNumber minFractionDigits="3"/>
 </h:outputText>

 </rich:column>
 <rich:column sortBy="#{data.max}" style="text-align:left;" label="Maximum" >
 <f:facet name="header" >
 <h:outputText value="Maximum" />
 </f:facet>
 <h:outputText value="#{data.max}" >
 <f:convertNumber minFractionDigits="3"/>
 </h:outputText>

 </rich:column>

 <rich:column sortBy="#{data.total}" style="text-align:left;" label="Gesamt" >
 <f:facet name="header" >
 <h:outputText value="Gesamt" />
 </f:facet>
 <h:outputText value="#{data.total}" >
 <f:convertNumber minFractionDigits="3"/>
 </h:outputText>

 </rich:column>

 </rich:extendedDataTable>
</a4j:region>

</a4j:form>
</ui:composition>

so i removed the a4j:form and set on my page

 <a4j:form >

 <a4j:include viewId="#{AdminClient.page}" />
 </a4j:form>

but then the commandbutton doesn't work any more. what am i doing wrong?
