--------------------------------------
Trying this scenario with the schema that Tobias provided me and MySQL InnoDB
storage engine, I am getting the following error on Cayenne 3.0M6:

> 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.
