Andrus Adamchik updated CAY-1547:
---------------------------------
Description: Currently UuidRelationships are read-only. There's no easy way
to establish them in the code, especially if both from and to objects are NEW
and PK is not known. So I am going to add some handler code that does all the
backend magic. (maybe someday we make UuidRelationship a first class citizen in
Cayenne and this will be done differently, for now it belongs in
cayenne-lifecycle). (was: Currently UuidRelationships are read-only. There's

One possible subtask of this task is a PkQuery - a special query to reserve a
primary key for the object before commit. This will simplify the process of
transactional saving UUID "FK" , and seems like a useful utility in general.)
