Please help any one in this while converting xml to bean, here I am using betwixt.This xml contains normal data as well as collections data but normal data and some of collection data is populating in beans and some collection data is populating beans with null values.

XML response is :
<?xml version="1.0" encoding="UTF-8"?>
<Hostel noOfHostels="1">
roomNo="0004105232" roomLocation="2101086158" roomPlace="2622" bookedOn="08/27/2008 03:07:56 PM"
roomName="TAMIL NADU" quota="GN" class="SL" source="ndls" destination="mas"
day="28" month="08" year="2008" bordingdate="08/28/2008 12:00:00 AM"
internetServiceCharge="20.00" roomFare="2696.00" totalFare="2716.00" idPassenger="1">

<Passenger slNo="1" name="TEST" age="35" sex="m" concessionCode="BLANK" bookingStatus="RLWL 6" />
<Passenger slNo="2" name="aaaa" age="85" sex="m" concessionCode="NOCONC" bookingStatus="RLWL 7" />


and betwixt mapping is
MAPPING = new String(
"<?xml version=\"1.0\"?>"
+ "<betwixt-config>"
+ "<!--name of the class to map -->"
+ "<class\">"
+ "<element name=\"Hostel\">"
+ "<attribute name=\"noOfHostels\" property=\"noOfHostels\"/>"
//+ "<element name=\"HostelRoom\">"
+ "<element name=\"HostelRoom\" property=\"hostelRoom\" updater=\"addHostelRoom\" class=\"\"/>"
+ "</element>"
+ "</class>"
+ "<class name=\"\">"
+ "<element name=\"HostelRoom\">"
+ "<attribute name=\"roomNo\" property=\"roomNo\"/>"
+ "<attribute name=\"roomLocation\" property=\"roomLocation\"/>"
+ "<attribute name=\"quota\" property=\"quota\"/>"
+ "</element>"
+ "<element name=\"Passenger\">"
+ "<element name=\"Passenger\" property=\"passenger\" updater=\"addPassenger\" class=\"\"/>"
+ "</element>"
+ "</class>"
+ "<class name=\"\">"
+ "<element name=\"Passenger\">"
+ "<attribute name=\"slNo\" property=\"slNo\"/>"
+ "<attribute name=\"name\" property=\"name\"/>"
+ "<attribute name=\"age\" property=\"age\"/>"
+ "<attribute name=\"sex\" property=\"sex\"/>"
+ "<attribute name=\"concessioncode\" property=\"concessionCode\"/>"
+ "<attribute name=\"bookingstatus\" property=\"bookingStatus\"/>"

+ "</element>" + "</class>"
+ "</betwixt-config>");

and i created 3 POJOs

//included updater
public void addHostelRoom(BookedTicket bookedTicket) {
(this is arrayList)hostelRoom.add(bookedTicket);
public void addPassenger(BookedPassenger passenger){
(this is arrayList)passenger.add(passenger);

Here noOfHostels and passenger collection is populating properly but HostelRoom collection is not populating please help in this

to parse this we used

public static Object xmlToBean(Object object, String xml)throws Exception{
BeanReader beanReader = null ;
try {
beanReader = new BeanReader();
//Set the ConvertUtils Object for String Conversion of the Default primitive classes
.setObjectStringConverter(new ObjectStringConverter());

beanReader.getBindingConfiguration().setValueSuppressionStrategy(new AttributeValueSuppressionStrategy());
String temp = (String)object.getClass().getField("MAPPING").get(object);
beanReader.registerMultiMapping(new InputSource(new StringReader(temp)));

Object parsedObject = beanReader.parse(new StringReader(xml));

return parsedObject;
