> Hi,
> In a multi-valued property of type REFERENCE, when its values are changed most of the
references are lost upon save().
> I can´t attach a test case, but here is what I´ve been able to test:
>    1. REFERENCE property has values [A, B] (A and B being node UUIDs).
>    2. A new reference (to node C) is appended to the array of values. New value should
be [A, B, C].
>    3. save().
>    4. Reopen session and reload.
>    5. New value is [C]. References to A and B are lost.
> I´ve checked that the PersistenceManager gets a NodeReference object with just one reference
to node C, so the bug must be before the store().
> I don´t know the internals of Jackrabbit, but I´ve found a possible source of the problem
in o.a.j.core.version.VersionManagerImpl#setNodeReferences().
> When it "filters out" version storage references it also wipes out previous references
to A and B in the example above.
> One thing that has worked for me is to remove the not (!) in the condition:
>                 if (!hasItem(id.getParentId())) {
>                     refs.addReference(id);
>                 }
> But now even version storage references are persisted (and this shouldn´t be happening?).
> Anyway, please check whether that solution is OK.
> A patch file to change the condition is attached.
> Thanks a lot.
