It seems to work fine ...
Is the lastest version more like a 1.0 release Or a 1.0 RC06 ???
Well! We (currently) don't plan a rc6 version. There some unsolved problems with odmg-api and a newly concurrency problem of object materialization with auto-retrieve references in conjunction with ObjectCacheDefaultImpl class. When these problems solved, we will label a new "final 1.0" branch from CVS head (All made statements without guarantee ;-)).

Hello There is a problem on the MtoNCollectionPrefetcher .
Description :
Input a MtoN relation in an Oracle database All the ids are SQL NUMBER and are declared as BIGINT in the
repository.xml.
The problem is that the Prefetecher use a ReportQuery in the method prefetchRelationship but use the class descriptor ( in the associateBatched method ) for generating identity .
Identity on Object A using the ReportQuery : 2 BigInteger ( using the JdbcTypesHelper and the MetaDatas of the statement ) Identity on Object A using the ClassDescriptor : 2 Long
The equal method of the identity return false even with the same ids ... So access to the maps childMap and ownerIdsToLists ( in associateBatched
) cause NPE because returning null values .
I think may be the mapping of the good type of the ReportQuery result is missing ???
Here is a part of the stack :
