Hi all,
I am using mysql with all database generated pks and auto_increment.
This works fine for all tables except join tables. When accessing a join
table cayenne tries to access the AUTO_PK_TABLE rather then relying on the
auto_increment.
My join tables are configured identically :

I am attempting to use database generated IDs with Cayenne 3.0M5 and

Even more problematic is that the SQL generated seems invalid:

Two items for the Modeler:
1) Is there a reason it set to use a FileBrowser rather the the
FileDialog which is more powerful and 'user friendly' on Mac/Win?
2) Whichever we use should default to the users homedir.

This will diff the db against your current current map. You can then,

This I think may be more of a cayenne problem. You have to reload the
object to destroy the cayenne cache using something like RefreshQuery.
Thats what I have to do in many cases. Like this:

context.commitChanges();
context.commitChangesToParent();

Does Cayenne allow for the creation of a compound PK? I searched the
