Hello, I have a model Person with two accessors, one is initialized as float. In Interface builder I did a bound between accessor and a TableColumn (which one have a NumberFormatter). Everything ok but when I try store in with NSKeyedArchiver.archivedDataWithRootObject it fails saying:

Exception detected while handling key input.

can't convert NSDecimalNumber into Float

*** -[NSKeyedArchiver finalize]: warning: NSKeyedArchiver finalized without having had -finishEncoding called on it.


What I'm doing wrong? I should cast it or initialize the value as NSDecimalNumber instead of float?


Thanks.
