Furthermore I extended AjaxEditableLabel an overrode suggested methods:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import da.service.CartManagement;
import wicket.component.model.DatePropertyColumn;
public class EditableQuantityPropertyColumn extends PropertyColumn {
CartManagement cartmanagement;
/**

private static final long serialVersionUID = 1L;
static Logger logger =
LoggerFactory.getLogger(DatePropertyColumn.class);
public EditableQuantityPropertyColumn(IModel model, String sortOrder,
String propertyExpression) {
super(model, sortOrder, propertyExpression);
}
public void populateItem(Item item, String componentId, IModel model) {
IModel m = createLabelModel(model);
item.add(new QuantityLabel(componentId, m));
}
protected IModel createLabelModel(IModel embeddedModel) {
IModel m = super.createLabelModel(embeddedModel);
return m;
}
public CartManagement getCartmanagement() {
return cartmanagement;
}
public void setCartmanagement(CartManagement cartmanagement) {
this.cartmanagement = cartmanagement;
}
}
class QuantityLabel extends AjaxEditableLabel
{
static Logger logger = LoggerFactory.getLogger(QuantityLabel.class);
CartManagement cartmanagement;
public QuantityLabel(String id, IModel model)
{
super(id, model);
}
@Override
protected void onSubmit(AjaxRequestTarget target)
{
logger.debug("Model class=" + getModel().getClass());
super.onSubmit(target);
// cartmanagement.updateQuantity(getModel());
}
public CartManagement getCartmanagement() {
return cartmanagement;
}
public void setCartmanagement(CartManagement cartmanagement) {
this.cartmanagement = cartmanagement;
}
@Override
protected void onModelChanging() {
super.onModelChanging();
}
@Override
protected void onModelChanged() {
super.onModelChanged();
}
}
