Hi Again

Now the issue of the day is..
My Mediator dont listen for CUSTOM events....
Here is the scenario:
I have my view that dispatch an Event like this:
private function buscarPersonaRfc():void{
var evtObj:BusquedaRFCEvent=new BusquedaRFCEvent("BusquedaRFCEvent",txtRfc.text);
dispatchEvent(evtObj);
}
and in my Mediator i have..
override public function onRegister():void{
//Referencia a la aplicacion principal
APPNAME=BusquedaPersonas.NAME;
buscarPersonaProxy=facade.retrieveProxy("BuscarPersonaProxy") as BuscarPersonaProxy;
buscarPersona.addEventListener("BusquedaRFCEvent",PBuscarPersona);
}
When i click on the propper button it doesnt happen anything!...
the strange thing its that if i dispatch another event (no custom event), an event like..
private function buscarPersonaRfc():void{
dispatchEvent(new Event("buscaPersonaNombre",true));
}
and in my mediator i have..
override public function onRegister():void{
//Referencia a la aplicacion principal
APPNAME=BusquedaPersonas.NAME;
buscarPersonaProxy=facade.retrieveProxy("BuscarPersonaProxy") as BuscarPersonaProxy;
buscarPersona.addEventListener("buscaPersonaNombre",PBuscarPersona);
}
IT WORKS!!!....how am i missing. Do i have again register all the mediators in the ApplicationMediator???
Any guidelines?? Thanks to all, i am starting with this framework

sorry for all my quiestions
