Hate to answer my own question, but I think the proper relation for:
@OneToMany
@Cascade(CascadeType.ALL)
public Collection<GrantedAuthorityBean> getGrantedAuthorities() {
return grantedAuthorities;
}
is:
@ManyToMany( cascade={CascadeType.PERSIST, CascadeType.MERGE} )
You then need to persist your GrantedAuthorityBean independently from
UserDetails, but that makes sense, and it solves the problem of the
GrantedAuthorityBean and the join table exploding with duplicate info.
Thanks,

In the provided example for tapestry-acegi, I have a question about
the GrantedAuthorityBean table. That is, if I add more users which
share roles, each role will create a new row in the GAB table. How
can this be avoided?
I've tried making the authority unique:
@Table(uniqueConstraints = [EMAIL PROTECTED](columnNames =
{"authority"})})
but hibernate is not clever enough to realize that it should reuse
existing roles, and just throws a constraint exception. I'm looking
at interceptors now. I guess this is really a hibernate question,
but I thought that someone here might have encountered this issue,
given its context in tapestry-hibernate.
Thanks,
