JSF + Richfaces 4.2.0 - Primeiro request não acessa o Bean

Bom dia estou desenvolvendo um rotina em um projeto que utiliza JSF 2.0, Richfaces 4.2.0 .
Eu criei um rich:popupPanel que contém um rich:tabPanel, uma das tabs deste rich:tabPanel possui um rich:dataTable com uma listagem comum, em uma das coluna eu criei um a4j:commandLink que deve executar um cancelamento no bean, porém no primeiro acesso a esse a4j:commandLink ele não acessa o Bean, a partir do segunda acesso ele executa normal e completa a requisição corretamente.
Quem sabe alguém aqui do forum ja passou por este problema.
Abaixo segue meu Código:
código do popup:

Eu não li o seu código, mas você por acaso tem um <h:form> dentro de outro? talvez pelo uso de facelets.

Rodrigo, eu verifiquei o código da nossa página template e ele não possui nenhum h:form como é possível ver no código abaixo.

eu acho que o problema está no rich:popupPanel, porque fora dos pop-ups do projeto tudo funciona corretamente, porém eu não tenho certeza disso porque em várias buscas que fiz pela internet não encontrei nenhum relato de problemas deste tipo com rich:popupPanel.
Obrigado pela dica Rodrigo.

[/code]Veja que você fecha 2 forms aí, e estão 1 dentro do outro…

Rodrigo, o meu commandLink está fora deste segundo form, mas como você apontou ele eu retirei para ficar correto, porém continua não funcionando, acredito que mesmo estando incorreto, este segundo form não estava influenciando no funcionamento, mas mais uma vez obrigado pela dica.

Vou dar mais uma vasculhada no google e aqui no forum para ver se acho alguém com problema similar.

é, fica meio difícil de saber assim…

qual é o commandLink em questão?

Por que você está usando a4j:region ?

Rodrigo desculpe não informar direito o commandLinlk que não funciona. O commandLInk que está com problema é o que está na column:

<rich:column style="width:5%"  
                        rendered="#{userContextBean.isAccess(6,2)}">  
                        <f:facet name="header" style="width:5%">  
                            <h:outputText value="#{msg.pst_cargo_botao_cancelar}" />  
                        </f:facet>  
                        <a4j:region id="regioActionCancel">  
                            <a4j:commandLink styleClass="no-decor"  
                                render="tb_commands messagesCancelCommand messagesCancel"  
                                actionListener="#{commandCancelBean.cancelCommands}"  
                                execute="@this" onclick="#{rich:component('statPane')}.show();" onerror="#{rich:component('statPane')}.hide();"  
                                oncomplete="#{rich:component('statPane')}.hide();if(#{facesContext.maximumSeverity!=null}){#{rich:component('messagesCancelCommand')}.show();}"  
                                rendered="#{userContextBean.isAccessVehicle(lc.vehicle.plate,5) or userContextBean.isAccessVehicle(lc.vehicle.plate,6)}">  
                  
                                <h:outputText value="#{msg.pst_cargo_botao_cancelar}" />  
                                <f:attribute name="return_ws" value="#{lc.returnWs}" />  
                                <f:attribute name="logObj" value="#{lc}" />  
                            </a4j:commandLink>  
                        </a4j:region>  
                    </rich:column>  

o a4j:region eu coloquei na tentativa de fazer funcionar, originalmente ele não estava mas também não funciona sem o a4j:region.
Nós já tivemos este problema do request em outros pop-ups mas como eram casos onde havia algum outro tipo de interação como preenchimento de algum campo texto eu resolvi colocando um a4j:ajax no evento blur ai quando ia dar submit o primeiro request que falha já tinha sido executado no evento blur, e o submit funcionava pois era o segundo request. Só que neste caso eu não tenho nenhum tipo de interação, o usuário abre a aba de cancelamento de comandos e já vai direto cancelar.
