> When adding an item to a collection for which the owner is fetched as READ_ONLY the version update fails if the owner class has a parent class (with a join strategy), but without parent it works.
> The problem is that the AbstractEntityPersister.getTableUpdateNeeded() returns with getTableHasColumns() (line 2748) when the owner is fetch as READ_ONLY. For a single table this probably works by luck.
> But what is the correct behavior? Should it be possible to update an READ_ONLY fetched owner's collection?
