Hi,
i have the same issue with Cayenne 2.0 :
Some objects are inserted and added in a commited object's to-many
relationship.
An exception occured, we rollback the changes but the new objects remain in
the to-many relationship
as transient objects !
Is this a feature or a bug ?
Is there a clean workaround ?
Thanks for your answers
