Description

Cannot persist entity with identity column. To reproduce, create a simple object with identity column

@Entity
@Table(name="JpaType")
public class JpaType implements Serializable
{
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="Id")
private Integer id = null;

@Column(name="Name")
private String name = null;

public Integer getId()

{ return id; }

public String getName()

{ return name; }

public void setName(String name)

{ this.name = name; }

}

create table JpaType (
Id int identity(1, 1) not null
, Name varchar(50) null
, constraint JpaType_PK primary key (Id)
)

JpaType jpa = new JpaType();
jpa.setName("Test 1");
em.persist(jpa);
em.flush();

It works OK if I remove identity column (and set ID myself).
