Hi Mike,
I don't think it is a specific Texo problem (cascades have different meanings and there are pros/cons to different
settings in different situations). But maybe the mapping can be generated in such a way that this problem does not occur
directly, although afaics the orm.xml is fine.
Is this something I can easily try myself? If you can send me a zipped project directly by email with a testcase I can
run then I can try to reproduce this.
There is lots of info on jpa/orm on the internet. The spec is quite readable, specifically the part where the
annotations are explained, chapters 11 and 12 (see attached):

Yes please do enter a bugzilla, I am surprised as persist, merge and refresh are the most common one, the other ones
(remove, refresh, detach) make less sense.If you enter a bugzilla then I will add refresh and detach, remove just does
not make sense for most many-to-ones...
