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<IncomeDetail>>
currentIncomeList = new
PropertyModel<List<IncomeDetail>>(sectionThreeModel, "incomes");
final PropertyModel<List<IncomeA>>
populateIncomeList = new
PropertyModel<List<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().
