a4j:commandButton doesn't invoke action method

[edgarms_ver_mx]

Hi I newbe on Richfaces, I found a lot information about this error but any solution provided in the others discussions solved my problem.

The next commandButton is working fine:

                                <a4j:commandButton rendered="#{adminFacturasBean.tipoFormFormaPago eq 1}"

                                                   value="Agregar Cuenta"

                                                   action="#{adminFacturasBean.agregarCuentaPagoTrans}"

                                                   render="mensajeErrorFormaPago"

                                                   execute="formaPago"

                                                   oncomplete="if (#{!adminFacturasBean.mostrarMensaje}) {#{rich:component('formaPago')}.hide(); #{rich:component('adminCuentas')}.hide();}"/>

But the next commandButton is not working:

                        <a4j:commandButton rendered="#{adminFacturasBean.tipoForm eq 1}"

                                           value="Crear"

                                           action="#{adminFacturasBean.crearFactura}"

                                           render="mensajeErrorFacturas, tablaFacturas"

                                           execute="crearElemento"

                                           oncomplete="if (#{!adminFacturasBean.mostrarMensaje}) {#{rich:component('crearElemento')}.hide();}"/>

I don't understand why is not working because I was working fine at the beggining, now the action method is not invoked.

Can someone help me ??

Thanks a lot in advanced.

[UPDATE]

I was investigating and I found the button works on second click...

I found some information that points this behavior to one bug in RF, is that true ??

If so, how can I avoid it ??

Thanks.

I found the solution, the problem was asociated to multiples forms in the same web page.

https://community.jboss.org/message/733138

I think is a good idea to have one form for each section instead of one form for the whole page but, it's working !!

Thanks.
