unrecognized selector sent to instance

Hi, I am having a strange problem of my class declaration. I used to declare some methods of a class in a category, "Private". After I have done some refactoring work (basically moving some classes into another framework), it seems those methods declared in the category, "Private" do not belong to the object anymore. If I load the code in my debugger and try to invoke a method declared as "Private", the program receives a doesNotRecognizeSelector error and crashes after receiving the signal SIGTRAP. And if I move those methods into the main implementation of the class, it all works out. Any idea why is that? Thanks for your help. BR, Pan
