Distributed Objects: Direct call vs. KVC

[Philip Mötteli]

Hi


I have a proxy of an object, which has a method -aMethod. When I call 
it directly, I have the following error:

	NSInvalidArgumentException: NSDistantObject(instance) does not 
recognize aMethod


When I call it via KVC ([anObject valueForKey:@"aMethod"]), everything 
works.
Is this, because I have the method -valueForKey: in a protocol? Do I 
have to define a protocol for every object, for which I call a method 
over DO? I thought, that when I don't have a protocol defined, I would 
only have the overhead of one round trip more and not an 
NSInvalidArgumentException.
If this is not the problem, why this exception?


Thanks for helping me!
Phil
