Hi Dennis, Thanks for your investigation. I think in order to be able to fully understand and hopefully reproduce the problem, I would probably need the following:
- DDL of the UPLOAD table - The generated classes for the UPLOAD table - The converters that are involved here 2013/4/14 Dennis Fischer <[email protected]>: > Oh boy, > > taking a look at jooqs source code showed me the true problem: > http://www.jooq.org/doc/3.0/manual/code-generation/custom-data-types/ > describes how to use the "calendar converter" - well I did so.

I don't think that this is the actual problem here. Yes, quick-fixing your generated code will work because of the above. But the point is still that jOOQ doesn't seem to know how to convert from Long -> Timestamp -> GregorianCalendar, even if it should.
