How can I add a new enum value to a field in QuickFIX/J?

Question

I want to add a custom enum value to a field in Quickfix.

For this purpose, I added new field (NEW_VALUE) to field (DeleteReason) on xml file. But this new enum field is not recognized on the app.

    <field number='285' name='DeleteReason' type='CHAR'>
        <value enum='0' description='CANCELLATION' />
        <value enum='1' description='ERROR' />
        <value enum='2' description='NEW_VALUE' />
    </field>

Note: <value enum='2' description='NEW_VALUE' /> is added by me.

Do I need an operation for processing new xml file (we added new unrecognized field) or is it impossible adding new enum value?
