Hi Andrus,
I post on the mailing list with a new mail adress, because my provider
sucks....
I will try to detail more what i do, so you can reproduce this in your
test case. Maybe i'ts because you don't have prefetching or "to dep PK".
There is a relationship between MasterJob--->MasterJobAux where i
checked "To Dep PK" since no ARTIST_AUX rows can exists without
corresponding MasterJob.
When i fetch a MasterJob i have added a prefetch for MasterJobAux :
query.addPrefetch(MasterJob.RELATED_MASTER_JOB_AUX_PROPERTY);
Code I use to get/create/delete MasterJobAux
protected MasterJobAux createAux(ILookupFieldCodes fieldCode,
Short seqNo, String value) {
MasterJobAux aux =
MasterJob.this.getObjectContext().newObject(MasterJobAux.class);
aux.setScheduleId(MasterJob.this.getScheduleId());
aux.setJobName(MasterJob.this.getJobName());
aux.setJaFieldCode((int) fieldCode.getID());
aux.setJaSequenceNumber(seqNo);
aux.setJavalue(value);
aux.setRelatedMasterJob(MasterJob.this);
return aux;
}
protected List<MasterJobAux> fetchAuxList() throws
OpconException {
return MasterJob.this.getRelatedMasterJobAux();
}
protected void deleteAux(MasterJobAux toDelete) throws
OpconException {
MasterJob.this.removeFromRelatedMasterJobAux(toDelete);
MasterJob.this.getObjectContext().deleteObject(toDelete);
}

To reproduce the problem :
1) Fetch MasterJobAux using the relationships
MasterJob.getRelatedMasterJobAux();
2) delete/create some MasterJobAux
MasterJob.removeFromRelatedMasterJobAux(toDelete);
MasterJob.getObjectContext().deleteObject(toDelete);
3) Rollback
4) re-Fetch MasterJobAux using the relationships
MasterJob.getRelatedMasterJobAux();
I get TRANSIENT objects, you can look a the SQL log attached where there
is some others details.
Thanks.

Hi,
Sorry, you posted this earlier and looks like nobody replied yet.
So my question is : is this normal to get *TRANSIENT* objects from a
relationship after a rollback ?
No, it is not normal. I just created a test case to reproduce it and
things seem to be working ok:
PaintingInfo info = ctxt.newObject(PaintingInfo.class);
info.setTextReview("XXX"); p1.setToPaintingInfo(info);
assertSame(info, p1.getToPaintingInfo()); ctxt.rollbackChanges();
assertNull(p1.getToPaintingInfo());
Does it look like the scenario that you have, or am I missing something?
Thanks, Andrus

Hello again !
I have a strange thing happening in Cayenne 3.0M4 : I have two tables
ARTIST and ARTIST_AUX where extended artist's properties are stored.
There is a relationship between ARTIST--->ARTIST_AUX where i checked
"To Dep PK" since no ARTIST_AUX rows can exists without corresponding
ARTIST.
I have also a addPrefetch(ARTIST_AUX) when i retrieve ARTISTs.
In my "artist editor" I create ARTIST_AUX rows at need and when an
error occurs i do a rollback(). The strange thing is that when i
refetch ARTISTS_AUX with the relationship, instead of getting only
existing ARTISTS_AUX, i get also the ARTISTS_AUX created before the
rollback() with the *TRANSIENT* state and no ObjectContext associated.
So my question is : is this normal to get *TRANSIENT* objects from a
relationship after a rollback ?
Thanks Laurent Marchal.
