> I get an error in the CayenneModeler 1.2.4  when reverse engineering my schema partially.
> CayenneModeler INFO  [Thread-13 04-27 15:02:50] org.objectstyle.cayenne.modeler.dialog.db.DbLoaderHelper: Exception on reverse engineering

> 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.
