I believe I have found a Hibernate bug. I know that 99% of "bugs" are actually user errors. However...
I get the following exception. Note that the relevant column is set to "NOT NULL"; there are absolutely no NULL values in the database. I get this error both when doing a query and with a record create.
Hibernate: 3.0.5
MySQL: 4.1.13
If anyone could help resolve, I would greatly appreciate it.
