Subject RE: Virtual Entity
Date Thu, 24 Jun 2010 13:10:45 GMT
Yes it does have an @id but I have a base entity that creates them
automagically (Base64 representation of the current system time), so it is
sort of like generated value type. My getters martial the data to the
virtual field is retuned in the structure I expect and I guess you could do
the same thing with setters if you wanted.

So your virtual entity has no @Id? Or you are using a bogus property as the
id? Does "nothing but getters" imply read-only and JPA treats it
differently? I actually imagined not putting getters or setters in it.
