[flexcoders] proxy callproperty problem

[Webdevotion]

Hello,

I've been staring into the dark since yesterday on this one.
I extend Proxy and implement IEventDispatcher


public dynamic class RemotingProxy extends Proxy implements
IEventDispatcher{
  // my class
}



somewhere in my class I have the callProperty method


flash_proxy override function callProperty( methodName:* , ... args ):*
{
    return serviceProxy[methodName.toString()].apply(serviceProxy,params );
}

I always run into this compilation error.
*Error:* TypeError: Error #1009: Cannot access a property or method of a
null object reference.
