Subject [jira] [Created] (OPENJPA-2221) Use of AbstractValueHandler map() causes exception on find()
Date Thu, 28 Jun 2012 14:47:44 GMT
Dianne Richards created OPENJPA-2221:
----------------------------------------

             Summary: Use of AbstractValueHandler map() causes exception on find()
                 Key: OPENJPA-2221
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2221
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 2.1.0
            Reporter: Dianne Richards
            Assignee: Dianne Richards
             Fix For: 2.1.1


When a value strategy implemented by a subclass of AbstractValuehandler overrides the map()
method, an exception occurs on a find() if the strategy is implemented on an id field. The
method returns a Column[].

Presumably the exception would occur on other fields if they were part of the query.

The DBDictionary setUnknown() method needs to handle input of an Object[].
