Setting a parameter in a bulk update with a value of type Enum throws an
exception
----------------------------------------------------------------------------------
Key: OPENJPA-289
URL: https://issues.apache.org/jira/browse/OPENJPA-289
Project: OpenJPA
Issue Type: Bug
Affects Versions: 0.9.7
Environment: Windows XP SP2, Java 1.5.0_11, Hypersonic database
(hsqldb) 1.8.4
Reporter: Christian Defoy
Assume that Class Shape contains an attribute of type LineType (an Enum). When
trying to do a bulk update of the enum value using the following query
UPDATE Shape s SET s.type = :type
and setting the "type" parameter using the following:
query.setParameter( "type", Type.PLAIN );
the following exception is thrown:
Exception in thread "main" <0.9.7-incubating nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: The specified parameter of
type "class test.LineType" is not a valid query parameter.

There is a workaround: assuming that the database column is an integer, you can
use the ordinal value of the enum. This also assumes that the values of your
enums are in sync with their ordinal values.
