I found the issue. The @Id annotation in the owning class
(VelocityUserDefinedField.java) had to be directly on or above the
field. So where I initially had
@Id
@Column(name = "FieldNo")
private int fieldNo;
@Id
@Column(name = "UserID", nullable = false, insertable = false,
updatable = false)
private int userId;
when I changed it to
@Column(name = "FieldNo")
@Id
private int fieldNo;
@Column(name = "UserID", nullable = false, insertable = false,
updatable = false)
@Id
private int userId;
The error went away. I was able to reproduce it in a different project.
If someone else can replicate this also, I could file a bug if this is one.
Thanks
