Subject reverse engineering partially changed schema
Date Mon, 11 May 2009 14:24:44 GMT
Hi,

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
java.lang.NullPointerException

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
