list of NMTOKEN in xsd generating wrong method : convertToNMToken

This to report a bug and error on NMTOKEN Simple Type

In the xsd file if the NMTOKEN variable is used as list for example
<xs:simpleType name="ReferenceListType">
<xs:list itemType="xs:NMTOKEN" />
</xs:simpleType>
It generates the class Reference type :

fromString Method with following line

objectValues[i] =                            org.apache.axis2.databinding.utils.ConverterUtil.convertToNMToken(values[i]);

As per the reference symbole  convertToNMToken doesnt exist, looking at the abailable methos it should be convertToNMTOKEN(...)

Token is capital, once the java file is corrected the code compiles

can you please investigate why axis2 (i tested with 1.6.4 and 1.7.7, 1.7.8) we get this error

can you please fix ?

Kind Regards
