Subject [jira] Updated: (CAY-1547) cayenne-lifecycle: support for setting UuidRelationships
Date Wed, 09 Mar 2011 15:04:59 GMT

     [ https://issues.apache.org/jira/browse/CAY-1547?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.)
