Oh, yes, I missed the BaseB part.
:-) I stripped down from company sources and uglified the names.
So you're mapping unrelated inheritance hierarchies onto the same
table ?
Yes. This is kind of historically based, I designed for different
classes and tables, but there were 1 to {0,1} relations and our
database "guru" from the other department "optimized" them into one
table :-(
As the classes can be used independently, I tried out this way and it
worked.

queries for the base classes, collections that refer to one of the

all the better.
Seems to work in OJB without problems for my purposes.
As for the error message, for now you can turn off the XDoclet check
using the checks attribute as described here:#
It's not XDoclet complaining, but Torque, so is this a Torque issue?
The error message and stack trace (with -debug) is:
