FileUpload problema com a4j:commandButton

Front-end
#1

Olá pessoal, estou com o seguinte problema, tenho um formulário que tem alguns campos a serem preenchidos e um uploadfile e o botão de ok, o problema ocorre se eu colocar um arquivo para ser feito o upload, logo após terminar o upload o botão não funciona mais, o botão só funciona se eu não coloco nem um arquivo para fazer upload
segue o codigo


<body>
	<f:view>
    	<h:form id="form">
         	<rich:panel rendered="#{Controlador.atividadeAndamento == 'ape_09_38_56_630'}" id="ape_09_38_56_630" style="width:80%; height:100%; float: right; display: block;">
           		<rich:tabPanel switchType="server">

										allowFlash="true">
										<a4j:support event="onuploadcomplete" reRender="form"/>
									</rich:fileUpload>
									<a4j:commandButton value=" Ok 0003" action="#{ape_09_39_00_243.Verificacao}" reRender="form"/> 
								</rich:panel>
								
							</rich:panelBarItem>
                		</rich:panelBar>
             		</rich:tab>
           		</rich:tabPanel>
         	</rich:panel>

Não tenho idéia do que pode ser, pois o upload é concluido e se eu não utilizo o uploadfile o botão funciona normalmente

grato

é estranho pois no exemplo no site do richfaces parece funcionar normalmente o botao a4j:commandButton

<h:form>

O problema certamente vem do seu método de upload !
