The only referenced column is one of the *primary* key columns. I left
out the word "primary" in my previous reply.
To make sure I understand, are you saying that a primary key column
isn't a primary key column when part of a composite primary key? In
other words, only the complete set of prima
The spec says " referenced columns that are not primary key
columns...". Nothing in here says full or partial.
I completely agree with Sanne - its not a bug and it is something we have

Hi Vlad,

association.
WRT the second example, where the referenced columns are a subset of the PK
columns -- I understand there are better ways to model this.
In particular, since the subset of PK columns needs to be unique (
Hi,
For the OneToMany with @JoinColumn, the user can workaround this limitation
by just using the @ManyToOne on the child side on any column they want
and turning the unidirectional association into a bidirectional one. I
remember I tested it and it worked just fine.
For the OneToMany with @Join
Unidirectional OneToMany associations using @JoinColumn that reference
columns that are not PK columns is not currently supported.
The JPA 2.1 documentation for @JoinTable says:
"Support for referenced columns that are not primary key columns of the
referenced table is optional. Applications that
