ajax4jsf — GUJ

Ola pessoal seguinte tenho um selectOneMenu que popula um outro, e estou usando o ajaxJsf para isso , quando o meu managed-bean esta com a scopo session ele funciona blz … mas quando ele esta com o scopo request ele ate preenche o outro selectOneMenu mas quando peço pra atualizar ao inves dele ir pra acao, ele recarrega a pagina …

mas se eu nao alterar a opcao no selectOneMenu e manda atualizar funciona !

&lt;managed-bean&gt; 
        &lt;managed-bean-name&gt;Login&lt;/managed-bean-name&gt;
        &lt;managed-bean-class&gt;faces.LoginFace&lt;/managed-bean-class&gt;
        &lt;managed-bean-scope&gt;session&lt;/managed-bean-scope&gt;  
        &lt;managed-property&gt;
        	&lt;property-name&gt;systemFacade&lt;/property-name&gt;
        	&lt;value&gt;#&#123;systemFacade&#125;&lt;/value&gt;
        &lt;/managed-property&gt;   
  &lt;/managed-bean&gt;

 	 &lt;managed-bean&gt; 
        &lt;managed-bean-name&gt;Recadastrar&lt;/managed-bean-name&gt;
        &lt;managed-bean-class&gt;faces.RecadastrarContatoFaces&lt;/managed-bean-class&gt;
        &lt;managed-bean-scope&gt;request&lt;/managed-bean-scope&gt;
		&lt;managed-property&gt;
        	&lt;property-name&gt;login&lt;/property-name&gt;
        	&lt;value&gt;#&#123;Login&#125;&lt;/value&gt;
        &lt;/managed-property&gt;
		&lt;managed-property&gt;
        	&lt;property-name&gt;recadastrarContatoFacade&lt;/property-name&gt;
        	&lt;value&gt;#&#123;recadastrarContatoFacade&#125;&lt;/value&gt;
        &lt;/managed-property&gt;
   &lt;/managed-bean&gt;

tags :

&lt;h&#58;panelGroup id="grupoEstado"&gt; &lt;h&#58;selectOneMenu id="estadoSelectOne" value="#&#123;Recadastrar.estadoSelectOne&#125;" &gt; 
            &lt;f&#58;selectItems value="#&#123;Recadastrar.estado&#125;"/&gt; &lt;a4j&#58;support  event="onchange" action="#&#123;Recadastrar.filtraMunicipio&#125;" reRender="groupMunicipio" /&gt; 
            &lt;/h&#58;selectOneMenu&gt; &lt;/h&#58;panelGroup&gt;

&lt;h&#58;panelGroup id="groupMunicipio" &gt; &lt;h&#58;selectOneMenu id="muniSelectOne" value="#&#123;Recadastrar.muniSelectOne&#125;"&gt; 
            &lt;f&#58;selectItems value="#&#123;Recadastrar.municipio&#125;" /&gt; &lt;/h&#58;selectOneMenu&gt; 
            &lt;/h&#58;panelGroup&gt;

me parece que ele carrega todos os objtos novamente .

valeu pela força!
