Support for single byte numbers broken
Apple Reference 3100683
ISSUE:
Specifying an attribute that mapped to a single byte external
database type with a value type of 'b' and NSNumber value class was
broken.
RESOLUTION:
This specific case has been enabled.
I filed this bug back in November when I was unable to model either a
FrontBase TINYINT or BYTE(1), both single byte datatypes, using a
Number value class and 'b' value type. I don't think the fix should
affect a boolean datatype, especially when modeled with as a 'c'
Number, but who knows?
I have always been somewhat uncomfortable modeling a datatype as a
Number when its concrete Java type would not be a Number subclass
(e.g., Boolean or java.math.BigDecimal). This makes me wonder whether
the class cast exception occurs when a Number is being cast to a
Boolean. Maybe the workaround would be to do as others have been doing
and model a boolean value as an 'i' Number (or maybe a 'b' Number since
this is supposed to be fixed).
Aloha,
Art
