Sorry, I meant Daniel :-)

Hi David,
Looks like a bug, can you enter one and include your model?
Unfortunately I can't think of a workaround besides generating
the tables yourself or pairing the model down to:
@Entity
class Key {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id_key", nullable="false") // (losing the TINYINT UNSIGNED
definition):
private Short id;
}
@Entity
class Attendance {
@JoinColumn(name = "idkey_atd",
nullable = true)
@ManyToOne(optional = false)
private Key key;
}
Cheers,
Guy

Hi guys,
I ran into this very weird behavior with EclipseLink as a JPA
2 provider. I suppose this is a bug, because Hibernate does
not have this kind of behavior.
So here is what I have:
@Entity
...
class Key ... {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id_key", columnDefinition="TINYINT
UNSIGNED NOT NULL")
private Short id;
...
}
Key is the first entity I have. The second one is Attendance,
which has a foreign key referencing to a key:
@Entity
...
class Attendance ... {
...
@JoinColumn(name = "idkey_atd", nullable = true)
@ManyToOne(optional = false)
private Key key;
}
Note that key columns is nullable. Well everything looks good
until I generate DDL, which will give:
... definition of Attendance table here ... idkey_atd TINYINT
UNSIGNED NOT NULL, ....
So it will ignore me saying that the key column in the
Attendance table can be NULL. Moreover, it will
ignore any column definition specified on the key column in
the Attendance entity whatsoever.
Is it a bug or am I doing something wrong? Once again
Hibernate generates the right DDL. If it's a bug, is there a
workaround?
Thanks!
