but if I add a class CustomerList

import java.util.ArrayList;
import java.util.Collection;

import org.apache.commons.betwixt.io.BeanCreateRule;
import org.apache.commons.lang.builder.ToStringBuilder;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

public class CustomerList {
 Collection customers =3D new ArrayList();
=20
 private static Log log =3D LogFactory.getLog( BeanCreateRule.class );
   =20
    public static void setLog(Log aLog) {
        log =3D aLog;
    }

=20
=20
=20
 public Collection getCustomers() {
  if (customers =3D=3D null) {
   customers =3D new ArrayList();
  }
  return customers;
  =20
 }
 public void addCustomer(CustomerBean newCustomerBean) {
  log.info("adding "+newCustomerBean);=20
  getCustomers().add(newCustomerBean);
 }
=20
=20
=20
 public String toString() {
  return ToStringBuilder.reflectionToString(this);
 }
=20
}

I leave CustomerBean.betwixt intact
I use this class to write CustomerBean3.xml


import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.io.StringWriter;

import org.apache.commons.betwixt.io.BeanWriter;
import org.apache.commons.betwixt.strategy.DecapitalizeNameMapper;
import org.apache.commons.betwixt.strategy.HyphenatedNameMapper;

public class WriteCustomerListApp {

    public static final void main(String [] args) throws Exception {
       =20
       StringWriter outputWriter =3D new StringWriter();=20
       outputWriter.write("<?xml version=3D'1.0' ?>");

        BeanWriter beanWriter =3D new BeanWriter(outputWriter);
  =20
        =
beanWriter.getXMLIntrospector().setAttributesForPrimitives(false);
        beanWriter.setWriteIDs(false);
        beanWriter.enablePrettyPrint();
        beanWriter.getXMLIntrospector().setAttributeNameMapper(new =
HyphenatedNameMapper());
  =20
        beanWriter.getXMLIntrospector().setElementNameMapper(new =
DecapitalizeNameMapper());
  CustomerList customerList =3D new CustomerList();
 =20
        CustomerBean customerBean =3D new CustomerBean();
        customerBean.setName("Diego");

        customerBean.addEmailAddre("A");
        customerBean.addEmailAddre("B");
        customerBean.addEmailAddre("C");
=20
  customerBean.addOrder(new Order(1));
  customerBean.addOrder(new Order(2));


        CustomerBean customerBean2 =3D new CustomerBean();
        customerBean2.setName("Paolo");

        customerBean2.addEmailAddre("E");
        customerBean2.addEmailAddre("F");
=20
  customerBean2.addOrder(new Order(4));
  customerBean2.addOrder(new Order(5));
  customerBean2.addOrder(new Order(6));

  customerList.addCustomer(customerBean);
  customerList.addCustomer(customerBean2);

        beanWriter.write("customerList", customerList);

 =20
        System.out.println(outputWriter.toString());
        FileOutputStream fos =3D new FileOutputStream( new File( =
"CustomerBean3.xml" ));
        PrintWriter out =3D new PrintWriter(new =
OutputStreamWriter(fos));=20
        out.println(outputWriter.toString());
        out.println();
       =20
        out.flush();
        out.close();
       =20
    }       =20


}

Result is following

<?xml version=3D'1.0' ?>
<customerList>
  <customers>
    <customer>
      <emailAddre>A</emailAddre>
      <emailAddre>B</emailAddre>
      <emailAddre>C</emailAddre>
      <name>Diego</name>
      <order id=3D"1"/>
      <order id=3D"2"/>
    </customer>
    <customer>
      <emailAddre>E</emailAddre>
      <emailAddre>F</emailAddre>
      <name>Paolo</name>/
      <order id=3D"4"/>
      <order id=3D"5"/>
      <order id=3D"6"/>
    </customer>
  </customers>
</customerList>

I try to read this file like that


import java.io.FileReader;
import java.util.Collection;

import org.apache.commons.betwixt.io.BeanReader;
import org.apache.commons.betwixt.strategy.DecapitalizeNameMapper;
import org.apache.commons.betwixt.strategy.HyphenatedNameMapper;

public class ReadCustomerListApp {
   =20
    public static final void main(String args[]) throws Exception{

     FileReader xmlReader =3D new FileReader("CustomerBean3.xml");

        BeanReader beanReader  =3D new BeanReader();
       =20
        =
beanReader.getXMLIntrospector().setAttributesForPrimitives(false);
        beanReader.setMatchIDs(false);
        beanReader.getXMLIntrospector().setAttributeNameMapper(new =
HyphenatedNameMapper());
        beanReader.getXMLIntrospector().setElementNameMapper(new =
DecapitalizeNameMapper());
         beanReader.registerBeanClass("customerList", =
CustomerList.class);
   =20
         beanReader.registerBeanClass("customer", CustomerBean.class);
    =20
    =20
         beanReader.registerBeanClass("order", Order.class);
=20

        CustomerList customerList =3D (CustomerList ) =
beanReader.parse(xmlReader);
 =20
        System.out.println(customerList );
    }
   =20
}

and I get the output=20
CustomerList@329f3d[customers=3D[CustomerBean@186c6b2[name=3DDiego,orders=
=3D[],emailAddres=3D[]], =
CustomerBean@1749757[name=3DPaolo,orders=3D[],emailAddres=3D[]]]]

that, is the methods addOrder and addEmailAddre are never called
