Off the top of my head, check they types of the keys to, as defined in the EOModel, to the M:N table and in the M:N table. Are all consistently Integer or Long in Java?

Meantime, I have played with another M:N, which works without a glitch (and which is modelled the same way as that one which does not, incidentally). Here, save-time, the snapshot does contain the proper related objects (and thus proper INSERTs are generated). The weird thing is that these objects *do not* come into the snapshot through the DatabaseContextDelegate.databaseContextShouldUpdateCurrentSnapshot method! It logs all right when the object is fetched, but the new (nor the old, of course) dictionary does *not* contain the relationship key at all -- precisely the same way it is with that relationship which does not work properly! Nevertheless, as mentioned above, save-time, the snapshot is all right. Couriouser and couriouser, Alice would say :-O Thanks and all the best, OC
