Core Data Problem

[Christiaan Hofman]

You've detailed the code part, but you didn't tell us what you did to  
test it. So we still do not know what actually failed. It may well be  
that your expectations are wrong. In fact, that seems to be the case  
from your explanation. You say that you have problems when the  
"NSManagedObject needs to set some data". That usually means changing  
a property. Than you go on describing methods to modify a  
relationship. So what are you actually modifying?
