A weird one here... I'm looking for advice on how to debug it. Using Cayenne 3.0M6 on Oracle 8 (but for once I don't think Oracle is the culprit).
One operation in our app commits a moderately large set of changes. 26 new or modified objects. ONE of the modified objects doesn't get any SQL generated and doesn't get written to the database. I've never seen this before. I skimmed through the outstanding Jira list. The discussion of CAY-1008 says, "Cayenne will not maintain the object graph consistency if there are multiple relationships between 2 entities, spanning the same set of joins." Could this explain the symptom? If so... Should I verify that our model has no redundant relationships? Are there any helpful tools for this, other than manually sifting through the DataMap? (It's 11,000 lines long.) Our model has a lot of reverse relationships that we don't use, left over from Cayenne 2. What's the design guideline now? Should we delete all such unneeded DbRelationships? Or should we keep them and add matching ObjRelationships for all of them? That is, would it be better to let Cayenne add runtimeRelationships or to avoid runtimeRelationships? I suppose I could step through the Cayenne's traversal of the object graph in the debugger, if nobody has any tips. Thanks, Bryan Lewis
