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.
