Subject [jira] [Created] (OPENJPA-2146) StateManager for Embeddable may throw Exception while initializing
Date Mon, 27 Feb 2012 22:19:50 GMT
StateManager for Embeddable may throw Exception while initializing

                 Key: OPENJPA-2146
             Project: OpenJPA
          Issue Type: Bug
          Components: kernel
    Affects Versions: 2.2.0, 2.1.1, 2.1.0, 2.0.1, 2.0.0, 2.0.2, 2.1.2, 2.2.1
            Reporter: Jody Grassel
            Assignee: Jody Grassel

When a complex graph of nested Embeddable are used in an application data model, an issue
may surface when the OpenJPA provider tries to instantiate an internal state manager that
represents the nested Embeddable. This issue results in an exception.  The Exception being
thrown is based on a generalized assertion that the nested Embeddable does not have an identity
associated to it since it is embedded in some entity which bears the identity.

Sample Exception:

<openjpa-2.0.2-SNAPSHOT-r422266:1084264 nonfatal user error> org.apache.openjpa.persistence.ArgumentException:
Cannot manipulate identity of type "<embeddable classname>": it's identity type is unknown.
