Re: Missing columns in result set

[Armin Waibel <ar...@apache.org>]

Hi Max,

do you use "ojbConcreteClass" setting in your persistent objects?
http://db.apache.org/ojb/docu/guides/advanced-technique.html#Mapping+All+Classes+on+the+Same+Table

We need more info, please post the metadata mapping for the classes.

regards,
Armin
