That's indeed correct, and I think it explains your problem: the old
index gets marked as modified, but as the store only sees the new one,
you get caught.

The fix is obvious:
    nresources.put(entry.identifier, entry) ;
should be:
    if ( entry.resource != null )
entry.resource.setValue("store-entry", entry);

I haven't compiled that yet, but it should work fine,
