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

>         beginTx();
>         // Create new
>         Person dain = new Person();
>         dain.setName("dain");
>         assertFalse(entityManager.contains(dain));
>         entityManager.persist(dain);
>         entityManager.flush();
>         assertTrue(entityManager.contains(dain));
>         // Find and verify
>         dain = entityManager.find(Person.class, "dain");
>         assertNotNull(dain);
>         assertEquals("dain", dain.getName());
>         // Delete
>         entityManager.remove(dain);
>         entityManager.flush();
>         assertFalse(entityManager.contains(dain));
>         // Recreate
>         dain = new Person();
>         dain.setName("dain");
>         assertFalse(entityManager.contains(dain));
>         entityManager.persist(dain);
>         entityManager.flush();
>         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;
>     }
> }
