Hi,
I'm having a little problem storing 1:n relationships. I have a relationship between class Review and class Evidence (1:n, a review has a collection of evidence and and evidence instance is only known in one review). When I create a new review, add the evidence (also new instances) and then store it (thus an insert for the review and an insert for every evidence instance) it works fine.
However, when I have an existing review, and I add new evidence to it, then locking the review does not store the evidence when I commit the ODMG transaction.
did you try first locking the review and then add the new evidence?
If this doesn't work try to lock the new evidence too after adding to review.
We are working on a better detection-algorithm for OJB1.0.2 or 1.0.3. You could try pre-1.0.2 from CVS (OJB_1_0_RELEASE branch, trunk is unstable 1.1). Some changes are checked in, but there are some issue with proxy collections (materialization on commit, ...). Hope I can fix all problems within 1 week.
regards, Armin
Why is the evidence stored when all objects are new, but not when the review exists and the evidence is new?
I found two work-arounds: 1. Explicitly lock all the evidence before committing the transaction. 2. Set auto-update="object" on the collection descriptor of the evidence inside the review class descriptor. But the documentation on this explicitly tells me *not* to set these (leave them default).
Is this a bug, or am I doing something wrong?
Thanks, Bart.
