Hi Michael, > you are right: The ORM metadata does not match the schema. A while ago, > I have fixed the same issue in classes "HashXXX", "ListXXX", "MapXXX" > etc. Obviously, I have overlooked the issue in class > "CollectionCollections". I'll fix this and I'll also check classes > "ArrayXXX". Thanks. It's only CollectionCollections that has this problem - I've already checked! Once this issue is fixed then all of the HashXXX, ListXXX, CollectionXXX, MapXXX, ArrayListXXX will need a fix adding for JDO-106 (I've commented the JIRA for that one with what the problem is there). -- Andy
