Well I dont know about that. you can add
public NSDictionary databaseContextNewPrimaryKey(EODatabaseContext
dbCtxt, Object object, EOEntity entity) {
to your application.java file and create your key values. I have done
this in the past for older projects.

Actually, there is no "primary" key. There are just the two "multi-
occurence" keys for the two foreign keys that are propagated by the
relationships.
I thought that was OK because that's the default when you create a
multi-to-multi join. And I do the exact same thing in another
model, which is the really perplexing part.
Do you think just creating a primary key in the database that is
auto incremented by MySQL would solve it?
Thanks Don.

This sounds like you have a compound primary key? A primary key
with more than one field or that your primary key is not something
that WebObjects can generate (string, etc).
The easiest way to use web objects is to create a primary key that
is a number and use it. Not use other fields in the table, just
create a number field that is the primary key this will save you
lots of hair pulling.

Hi,
I have a many to many join with flattened relationships that I
created using the new relationship wizard in Entity Modeler.
I then added a class property to the intermediary table and
changed the class name from EOGeneric record to an appropriate one
for the entity and package. Basically I need to know the "order"
of the objects in the table so I ascribed a position value.
After I create the object and attempt to save it I'm getting the
error "failed to provide new primary keys for entity". I've
checked the database and the table exists, the foreign keys are
created and I've actually compared it to another table/model where
I've done exactly the same thing without an issue.
I'm using ...
WO 5.4.3
Recent version of Wonder
MySQL 5.1.37, using the MySQL plugin supplied by someone on the
list .
OS X 10.6
