Christian Bauer closed JBSEAM-3135.
-----------------------------------
Resolution: Rejected
You do NOT want to override equals/hashcode on a persistent entity. This is only ever done in very exceptional cases. You want identity and equality guaranteed by a persistence context. I wrote two books about it so I don't feel like repeating the details here again.

> Considering the largish number of posts on the forum where "convertEntity doesn't work" or "the value doesn't stay selected", it could be nice to have a log.warn statement if s:convertEntity encounteres an entity without overridden equals/hashcode. If doable, that is.
