Re: [eclipselink-users] @BasicCollection not updating on merge 
Your mapping looks correct.  Could you include the code you use to
read/update/merge the object, and the version of EclipseLink you are using.

If you make the relationship lazy, or use a List instead of Set, or update
the managed object instead of merging, does it work?
