Hi Tobias,
This looks like a bug to me. Probably worth opening a bug report, but
the easiest thing would be to upgrade to Cayenne 3.0 for instance.
Chances are this problem is fixed there already.

I have updated a portion of the schema in the database. I delete the
DbEntities and ObjEntities of the tables that were changed.
I then click reverse Engineer from database. I get popups asking
whether to
overwrite existing Objects. I click "remember my decision" and NO.
at the end I get an error popup without a message. It is just
containing the
red error icon and a title reading "Error Reengineering Database".
This error does occur also when I select not to remember my decision
and
click through each popup one by one.
When reverse engineering the whole database, removing all
ObjEntities and
all DBEntities, before reverse engineering the error does not occur.
I have
many custom mappings redoing the existing mapping is not really an
option.
Any help highly appreciated.
thanks,Tobias
