Console error message during undo

[Aderstedt]

Using r1301 of BaseTen?, I get the following error when performing an undo on a single -setValue:forKey on a BXDatabaseObject. The undo is completed successfully.

(BaseTen?) [84906] PGTSFoundationObjects.m:62 -[NSObject(PGTSFoundationObjects) PGTSParameterLength:connection:] [0x20b020m] WARNING: Returning NULL from NSObject's implementation.

[tsnorri]

The warning indicates that an object is (supposed to be) deserialized from a result set fetched from the database, but some data type's class doesn't have a deserialization method.

I'm currently at WWDC but I'll look into this as soon as possible.

I wasn't able to reproduce this with a very simple test. I'll keep looking but if you can, please post a stack trace. You should be able to get one by setting a symbolic breakpoint to “-[NSObject PGTSParameterLength:connection:]”.

(In [1310]) Fixed a bug which caused a warning to be printed when NSNull was passed as a query parameter - Added a separate implementation for getting a NULL parameter for NSNull values. - Wrote a test for it. - References #204.

[tsnorri]

Sorry, I got this mixed up with +copyForPGTSResultSet:withCharacters:type:. Actually the method tries to serialize an object for an SQL query or command. I think I got this fixed, though. If not, the warning is now more informative.

[tsnorri]

I assume that this is now fixed. It happened in time for 1.7.
