   Hi guys!!!

   I've been trying to implement an event listener for type onEnterFrame, but it throws the following error:

   *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:
   '+[NSInvocation invocationWithMethodSignature:]: method signature argument cannot
   be nil'
   *** Call stack at first throw:

   And it follows with a weird list... (if it helps i can post it)

   The code of the event calling is:

   [self addEventListener:@selector(onEnterFrame:) atObject:self
   forType:SP_EVENT_TYPE_ENTER_FRAME];
    
   -(void)onEnterFrame{
   ...
   }

   can someone help me please?
   Thanks!!

   onEnterFrame:(SPEnterFrameEvent *)event{
   ...
   } -__-'

   Yeah, just remember each event listener will return some type of event to it's event handler (method). I tend to forget about the event argument everyone now and then :).
