Hi,
This is a bit larger problem with DO and selectors. Problem is that somewhere in gnustep DO wrong selector types are used. DO mechanism does not use selector types from remote object but from local runtime.

And here is the problem, because on the client side i have no type information in runtime. Should not the information from method signature be used instead of getting one from runtime?
Well, it might be classified as a base library, bug ... but any workaround within the base library would need changes to the objc runtime too, because the runtime will not pass the base library enough information (specifically the object being messaged) to determine the method types associated with the selector.
Within your code, it's likely to be easy to work around, because you probably know what object the message is being sent to ... so you can use -methodSignatureForSelector: to get the type information, then register a typed version of the selector with the runtime. Once you have done that, the DO system should use the typed version of the selector and it should all work.
Thanks for the suggestion, same was suggested few secods before you by alexm. I've put that workarouind in steptalk sources, if you are interested it is in Source/NSInvocation+additions.m:198 It seems to work for now.
So if it is considered a bug, should log it into savannah bug tracking? Or you will take care about that one?
Stefan
p.s.: i've posted two more DO related bugreports (about NSConnection and NSObject/NSMethodSignature) to savannah. They were sent to me by email, but not to the bug-gnustep. Is there something wrong with automatic delivery? To: header in email looked like:
