I have the same problem. I debug the code and as far as I can see it's crashing when it's trying to cast the data. The resultmap that I used is selecting proper data from the data base, but when it's trying to cast new class to the target class it's showing exception. If instead of declaration fe. Class1.Class2 i will use Class1.Class2.Id then I'm getting proper Id but I want to fill all the properties with the data, not only ID. Gilles/anyone can u please take a look at this?? I described exactly the same problem previously but Eddie done this better.
Regards, Jakub.
