I have a custom class MyClass, which essentially consists of several NSMutableArrays and other variables. I have a MyEntity object that has an ivar that belongs to MyClass. When I try to save the object, I get this stack dump:

Does anyone have any suggestions on what could be causing this? I think this is probably related to MyClass, but how do I fix it? Did I forget to write anything for this?
