Discovered that you can't embed entities in embeddable objects if the entity is managed. Haven't tried embedding un-managed entities in embeddable objects, though I imagine that's not a great idea. The the error message isn't all that obvious (attempting to persist object which already has an id

Discovered that embedded objects marked final are not persisted. I'm not exactly sure why that should the case. Is this a bug?     dmoshal David Moshal Final fields are treated as transient regardless of their type. If you mean that declaring the embeddable class as transient causes

Hi! I have the following persistence.xml. The problem is that ObjectDB loads all the classes in P1 (+ their embeddable classes). P2 is created properly, but P1 gets all entity classes (from P2 also). How can this be avoided, so that both P1 and P2 get just the classes that were specified to each

Hi there, The upgrade to 2.4.1_02 fixed the initial problem, however there still seems to be an issue. To me it appears that Embeddable might be being lazy loaded, but I cannot be sure. I have attached a testcase demonstrating this issue. Its failing on the merge. Thanks P. pedwards Paul Edwards
