Bug function getFieldArrayFromTaxRow($row, $tableName, $prefix)

Isn't a bug here?

$fieldType must be $fieldDataType

function getFieldArrayFromTaxRow($row, $tableName, $prefix)
    {
        $field = array();
        $field['fieldname'] = $row->taxname;
        $field['columnname'] = $row->taxname;
        $field['tablename'] = $tableName;
        $field['fieldlabel'] = $prefix . $row->taxlabel;
        $field['displaytype'] = 1;
        $field['uitype'] = 1;
        $fieldDataType = 'V';
        $typeOfData = $fieldType . '~O';

        $field['typeofdata'] = $typeOfData;
        $field['tabid'] = null;
        $field['fieldid'] = null;
        $field['masseditable'] = 0;
        return $field;
    }
