Andrus Adamchik commented on CAY-1224:
--------------------------------------
To add to the previous comment, the table it was failing on was in the mapping,
but not in the schema... We need to ensure we completely skip the existing
mapped entities that were not returned from the DatabaseMetadata on reveng run.
> reverse engineering partially changed schema shows empty error messge window

> 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.
