Problem creating DefineEngineMethod

Hey guys im having a problem trying to create a DefineEngineMethod. I need to pass to the engine an array that is createded in the editor that contains some objects.

.h

void        setNeiborhood(ArrayObject n);

ArrayObject getNeiborhood() { return neiborhood; };

ArrayObject neiborhood;

.cpp

DefineEngineMethod( Node, setNeiborhood, void, ( ArrayObject n ),, "Documentation string" )
{
	object->setNeiborhood(n);
}

DefineEngineMethod( Node, getNeiborhood, ArrayObject, (),, "Documentation string")

Tnx in advance
{
	return object->getNeiborhood();
}

error C2440: '<function-style-cast>' : cannot convert from 'ArrayObject' to 'ArrayObject *
