I have a piece of code that effectively does the same thing the following test does:

    private void newDeleteNew() throws Exception {
        beginTx();

        // Create new
        Person dain = new Person();
        dain.setName("dain");
        assertFalse(entityManager.contains(dain));
        entityManager.persist(dain);
        entityManager.flush();
        dain = entityManager.merge(dain);
        assertTrue(entityManager.contains(dain));

        // Find and verify
        dain = entityManager.find(Person.class, "dain");
        assertNotNull(dain);
        assertEquals("dain", dain.getName());

        // Delete
        entityManager.remove(dain);
        assertFalse(entityManager.contains(dain));

        // Recreate
        dain = new Person();
        dain.setName("dain");
        assertFalse(entityManager.contains(dain));
        entityManager.persist(dain);
        entityManager.flush();
        dain = entityManager.merge(dain);
        assertTrue(entityManager.contains(dain));

        // Find and verify
        dain = entityManager.find(Person.class, "dain");
        assertNotNull(dain); // <<<<<<< FAILS
        assertEquals("dain", dain.getName());

        commitTx();
    }

The test fails at the marked point, because the entityManager seems to think the "dain" entity is still deleted. I assume this type of code would work. Is this a bug or is my assumption wrong?

BTW, I'm using 0.9.8-incubating-SNAPSHOT

And here is my entity class:

@Entity
public class Person {
    private String name;

    @Id
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Thanks,
