Subject [jira] [Updated] (CAY-1625) Transient objects do not work in ROP apps
Date Tue, 06 Dec 2011 03:35:41 GMT

     [ https://issues.apache.org/jira/browse/CAY-1625?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrus Adamchik updated CAY-1625:
---------------------------------

    Attachment: 0001-CAY-1625-Transient-objects-do-not-work-in-ROP-apps.patch

Attaching a reworked patch based on John's. Changes:

1. Undid some new formatting so that the actual logic changes are more clear.

2. Removed an additional strategy change not directly related to handling of transients -
the 'safeEquals' check. This is not necessarily wrong, just an unrelated aspect requiring
its own discussion.

I am not applying the patch yet, as we'll need to ensure that all our client test cases are
switched to the new format and all the tests pass. Anybody feel free to perform this work
and create an extra patch here.

> In addition the problem referenced in CAY-1624, transient objects don't work when using
ROP because in the client template the relationship values (to-one and to-many) are   null
and are only initialized to non-null values when they are added to an ObjectContext.  By modifying
the template to initialize the relationship values to something non-null, transient objects
can be worked with locally (but not still saved?).  I don't know if that is the best solution,
but here's basically what I did.
