Key: OPENJPA-568
URL: https://issues.apache.org/jira/browse/OPENJPA-568
Project: OpenJPA
Issue Type: Bug
Components: kernel
Affects Versions: 1.1.0
Environment: This problem is reported with OpenJPA version:
$ java org.apache.openjpa.conf.OpenJPAVersion
OpenJPA 1.1.0-SNAPSHOT
version id: openjpa-1.1.0-SNAPSHOT-r420667:634150
Apache svn revision: 420667:634150
os.name: Windows XP
os.version: 5.1
os.arch: x86
java.version: 1.6.0_05
java.vendor: BEA Systems, Inc.
Reporter: Sandeep Shrivastava
Fix For: 1.1.0
The test deletes and instance and creates another with the same primary keys
and encounters an exception while making the new one persistent.
Here is the snippet from the test code:
pm.currentTransaction().begin();
MappingTest2 test2c = new MappingTest2();
test2c.setPk1(test2b.getPk1());
test2c.setPk2(test2b.getPk2());
pm.deletePersistent(test2b);
test4.getNManyMap().put("key2", test2);
test4.getManyManyMap().remove(test2b);
test4.getManyManyMap().put(test2, test2);
pm.makePersistent(test2c);
test4.setInverseOneOne(test2c);
MappingTest4 test4c = new MappingTest4();
test4c.setInverseOwnerOneOne(test2c);
test2c.setOneOneOwner(test4c);
pm.makePersistent(test4c);
pm.currentTransaction().commit();
The problem with this issue was that the JDO PersistenceManager.
makePersistent() is failing with the following exception:
[testlogic] <openjpa-1.1.0-SNAPSHOT-r420667:634150 nonfatal user error>
kodo.jdo.UserException: Operation attempted on a deleted instance.

Synopsis:
When the second call to pm.makePersistent(test2c) is made it is not attached
correctly. The effect of the prior pm.deletePersistent(test2b) which deletes
the object with the same key is kept in the persistence context and hence when
a relation is established with the deleted entity the third
pm.makePersistent(test4c) call throws the above exception.
The fix that I have is to correct the logic in the
org.apache.openjpa.kernel.VersionAttachStrategy.attach() method where it tries
to make a determination of whether this is a new object by also checking
whether the existing entity is deleted or not. And that fixes the problem. I
will attach it as a patch shortly.
Thanks
Sandeep
