[jira] Commented: (OPENJPA-828) Externalizer fails with ClassCastException with runtime enhancement

["Julien Kronegg (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENJPA-828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12696009#action_12696009 ] 

Julien Kronegg commented on OPENJPA-828:
----------------------------------------

Got this issue using Boolean->CHAR Y/N mapping for runtime enhanced classes under OpenJPA 1.2.1:

    @Column(name="flag", nullable=true, length=1)
    @ExternalValues({"true=Y", "false=N"})
    @org.apache.openjpa.persistence.Type(char.class)
    public Boolean getFlag() {
      ..
    }

Applying changes described in the following edits solved the problem:
http://svn.apache.org/viewvc/openjpa/trunk/openjpa-kernel/src/main/java/org/apache/openjpa/enhance/ReflectingPersistenceCapable.java?view=diff&r1=726926&r2=726927&pathrev=726927

This issue should also be solved in 1.2 and 1.3 branches...

> Several issues [1] are reported with @Externalizer field failing with ClassCastException. The issue appears only for runtime enhanced classes and not for build time enhancement.
