how to map list model within another list model by propertyModel

Hi , I have a xml class MC216 which has below object
 @XmlElement(required = true)
    protected IncomeInformation section3;
and 
IncomeInformation class have below list object
 protected List<IncomeDetail> incomes;

and this IncomeDetail class has below list object
 protected List<IncomeA> incomeEstimate;

Then, how to map the incomeEstimate by using PropertyModel. 
My code is below

final PropertyModel<IncomeInformation> sectionThreeModel = new
PropertyModel<IncomeInformation>(mc216Model, "section3");		
			final WebMarkupContainer populateIncomeInfo = new
WebMarkupContainer("populateIncomeInfo");
			final PropertyModel<List&lt;IncomeDetail>> currentIncomeList = new
PropertyModel<List&lt;IncomeDetail>>(sectionThreeModel, "incomes");
			
			final PropertyModel<List&lt;IncomeA>> populateIncomeList = new
PropertyModel<List&lt;IncomeA>>(currentIncomeList, "incomeEstimate");
			if (populateIncomeList.getObject() == null) {
				populateIncomeList.setObject(new ArrayList<IncomeA>());
			}

Here the currentIncomeList  can be mapped correctly  while
populateIncomeList can't. It throws exception 
when calling getObject().

Posted by Maxim Solodovnik <so...@gmail.com>.
I believe it is not possible
You have to create listview, each item will have model of IncomeDetail.
Then you can map IncomeA
