If I define an entity with a Double enclosed in an abstract data type (ex. (Double,Double)) and I insert a number with the decimal part == 0 (ex. (1.23, 4.0)), when I try to get the entity, an error is thrown:

*** Exception: PersistMarshalError "field <field name>: Expected Double, received: PersistInt64 <the int number>"

I'm using sqlite.
