I'm having problems understanding how to get entities to play nice
together. So, I'd like to find a good tutorial on how to work with
entity groups using JPA.
My specific issue, right now, is being unable to add a new entity to a
collection that is held by a parent entity. When I attempt to add a new
entity to the collection of children, I always get an error indicating
that the entity group is incorrect. I just haven't been able to find
any information about how to make this work.
Thanks for any tips/links.
