8 years ago While reviewing this post and comparing it with others, I figure it would be
best to
extract the specific schema from the project. Here it is in three parts.
@PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true")
public class A {
/**
* automatically generated primary key
*/
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName = "datanucleus", key = "gae.encoded-pk", value =
"true")
private String id;
@Persistent
private B1 b1;
<snip>
}
-------------------------------------
@PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true")
public class B1 {
/**
* automatically generated primary key
*/
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName = "datanucleus", key = "gae.encoded-pk", value =
"true")
private String id;
@Persistent(mappedBy="b1")
private A a;
<snip>
}
-------------------------------------------------
switch (testcase) {
case NEW_A:
{
// this test case works
pm.currentTransaction().begin();
A a = new A();
pm.makePersistent(a);
pm.currentTransaction().commit();
// unload populated variables
result = new TestCaseResult(a.getId(), a.getTimestamp());
}
break;
case NEW_B1:
{
// this test case works too
pm.currentTransaction().begin();
// lookup A
A a = pm.getObjectById(A.class, id);
B1 b1 = new B1( a );
//pm.makePersistent(a);
pm.currentTransaction().commit();
// unload populated variables
result = new TestCaseResult(b1.getId(), b1.getTimestamp());
}
break;
case NEW_AB1:
{
// this test case FAILS
pm.currentTransaction().begin();
A a = new A();
B1 b1 = new B1( a );
pm.makePersistent(a); // BLOWS UP HERE!
pm.currentTransaction().commit();
// unload populated variables
result = new TestCaseResult(a.getId(), a.getTimestamp());
}
