Reset values after submit with validation error in table components

[Branislav Kalas]

Hi,
I have table which is part of form.
Table extends 
org.apache.wicket.extensions.markup.html.repeater.data.table.DataTable.
In that table i use some AbstractColumns that renders input boxes, for 
example:

columns.add(new AbstractColumn<TakeBackPalletRollInfo>(new 
StringResourceModel("header.takenBackNetto", this, null)) {
            public void 
populateItem(Item<ICellPopulator<TakeBackPalletRollInfo>> cellItem, 
String componentId,
                    IModel<TakeBackPalletRollInfo> rowModel) {
                RequiredBigDecimalWithoutLabel takenBackBrutto = new 
RequiredBigDecimalWithoutLabel(componentId,
                        new PropertyModel(rowModel, "newChars.netto"));
                cellItem.add(takenBackBrutto);
            }
});

Data provider code:
public class TakeBackPalletProvider extends 
SortableDataProvider<TakeBackPalletRollInfo> {
    private TakeBackPallet takeBackPallet;

    public TakeBackPalletProvider(TakeBackPallet takeBackPallet) {
        this.takeBackPallet = takeBackPallet;
    }

    public Iterator iterator(int first, int count) {
        return takeBackPallet.getRollInfoList().iterator();
    }

    public int size() {
        return takeBackPallet.getRollInfoList().size();
    }

    public IModel<TakeBackPalletRollInfo> model(TakeBackPalletRollInfo 
object) {
        return new Model(object);
    }
}

After form submit, when validation error occurs  (like not filled 
required field) on some field which is not in table, values in table 
resets to it's initial values.
Where can be problem?
Thanks.
