> 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.
