Issue Type: Bug
Components: odata2-jpa
Affects Versions: V2 2.0.1
Environment: Windows 7, Apache Tomcat 7.0.56
Reporter: Riccardo
Priority: Critical
Hi,
I've some problems when i create entities with composite key using EmbeddedId
annotation. Below there are the classes causing the issue
{code:title=TestTable.java|borderStyle=solid}
@Entity
@Table(name="TEST_TABLE")
public class TestTable implements Serializable {
private static final long serialVersionUID = 1L;
@EmbeddedId
private TestTablePK id;
@Column(name="COL_GENERIC", length=20)
private String colGeneric;
public TestTable() {
}
public TestTablePK getId() {
return this.id;
}
public void setId(TestTablePK id) {
this.id = id;
}
public String getColGeneric() {
return this.colGeneric;
}
public void setColGeneric(String colGeneric) {
this.colGeneric = colGeneric;
}
}
{code}
{code:title=TestTablePK.java|borderStyle=solid}
@Embeddable
public class TestTablePK implements Serializable {
private static final long serialVersionUID = 1L;
@Column(name="COL_KEY1", unique=true, nullable=false)
private int colKey1;
@Column(name="COL_KEY2", unique=true, nullable=false)
private int colKey2;
public TestTablePK() {
}
public int getColKey1() {
return this.colKey1;
}
public void setColKey1(int colKey1) {
this.colKey1 = colKey1;
}
public int getColKey2() {
return this.colKey2;
}
public void setColKey2(int colKey2) {
this.colKey2 = colKey2;
}
public boolean equals(Object other) {
if (this == other) {
return true;
}
if (!(other instanceof TestTablePK)) {
return false;
}
TestTablePK castOther = (TestTablePK)other;
return
(this.colKey1 == castOther.colKey1)
&& (this.colKey2 == castOther.colKey2);
}
public int hashCode() {
final int prime = 31;
int hash = 17;
hash = hash * prime + this.colKey1;
hash = hash * prime + this.colKey2;
return hash;
}
}
{code}
When i get the $metadata, the application thrown the following exception
{color:red}
java.lang.NullPointerException

{color}
doing debugging i've seen that the field jpaEmbeddableTypes of the object
JPAPersistenceUnitMapType is null causing the NullPointerException.
This issue is not occur if i use the jpa annotation idClass instead of
EmbeddedId.
Could you help me please?
