Trouble with persistent element (extended schema) when field name does not match column name

[Tierney, Mary K (GE Healthcare)]

I have the following:

public abstract class Person {
...
                protected Boolean isActive;
...
}

Person table with column "IsInactiveFLAG" - char(1)

I am trying to use the Externalizer/Factory combo to transform the value into a 
Boolean for use in code.

In my orm.xml file (using the extended schema), I have the following:

<basic name="isActive">
                                                                <orm:column 
name="IsInactiveFLAG" column-definition="char(1)"/>
                                                </basic>
                                                <openjpa:attributes>
                                                                
<openjpa:persistent name="isActive"
                                                                                
externalizer="InvertedYesNoMapper.toDbValue"
                                                                                
factory="InvertedYesNoMapper.toValue"/>
                                                </openjpa:attributes>

I get the following error at runtime:

...Person.isActive" declares column "isActive", but this column does not exist 
in table "dbo.PERSON"

When I use attributes in the class, this all works fine.

Do I have to have matching field/column names in order to use this 
functionality in my orm.xml?
Please let me know if more information would be helpful.

Thanks,
