Re: [hibernate-dev] Is @SecondaryTable required when a join table is specified?
Actually, there are entities used in unit tests with @SecondaryTable defined with only
*-to-one attributes that refer to those tables:
org.hibernate.test.annotations.inheritance.mixed.File
org.hibernate.test.annotations.inheritance.mixed.SymbolicLink
org.hibernate.test.annotations.manytoone.OrderLine
org.hibernate.test.annotations.onetoone.Client
Unless I hear otherwise, I'll assume @SecondaryTable can optionally be defined if only
associations refer to it.

Hi Hardy,
I've seen lots of unit tests that have @SecondaryTable. I didn't make
the connection that it was non-association attributes that refer to
a secondary table.
Thanks for the clarification.
