Fetching from relationships returns TRANSIENT objects.
------------------------------------------------------
Key: CAY-1112
URL: https://issues.apache.org/cayenne/browse/CAY-1112
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0
Environment: Linux, Ubuntu 8.04, Cayenne 3.0.M4
Reporter: Laurent Marchal
Assignee: Andrus Adamchik
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.
