------------------------------------
Summary: InvalidStateException while merging a new Entity with a
GeneratedValue id
Key: OPENJPA-2443
URL: https://issues.apache.org/jira/browse/OPENJPA-2443
Project: OpenJPA
Issue Type: Bug
Components: kernel
Affects Versions: 2.3.0, 2.4.0
Reporter: Rick Curtis
Assignee: Rick Curtis
This problem only happens if you have an Entity with a Generated id that also
has the annotation @Basic(optional = false). If you create a new Entity and
then try to persist it via EntityManager.merge(...) call, you'll get the
following stack :
<openjpa-0.0.0-rnull fatal user error>
org.apache.openjpa.persistence.InvalidStateException: The field "id" of
instance
"org.apache.openjpa.persistence.jdbc.auto.AutoIncrementEntity@99883308"
contained a null value; the metadata for this field specifies that nulls are
illegal.
