[ http://jira.andromda.org/browse/HIB-126?page=comments#action_11888 ] Pietro Bonanno commented on HIB-126: ------------------------------------
This question was discussed in a post on the Forum, http://galaxy.andromda.org/forum/viewtopic.php?t=235 Chad Brandon said that this issue wasn't solved because he think embedded classes can't handle associations, and he suggested to use associations instead of embedding. IMHO this can't be the right way, because it involves an unnecessary join in the database. Really, embedded classes can handle associations. Hibernate treat these as normal entities. The only limitation is that they cannot (obviusly) have identity, but the rest is supported.
