How to use lazy initialize ModalWindow's Panel
in WebPage, add modalwindow when page init:
modalWindow.setContent(new
CheckoutOrderModalWindow(coOrder.getOrderBillNo(), mwCheckout));
CheckoutOrderModalWindow class create code:
public class CheckoutOrderModalWindow extends Panel {
public CheckoutOrderModalWindow(final CoOrder checkoutOrder, final
ModalWindow mwModalWindow) {
super(mwModalWindow.getContentId());
if (coOrder.getOrderOnline() == true) { //here throw nullpointexception
}
}
}
Because in the page initialization, CoOrder has not been created, thus
leading to WebPage initialize null pointer error.
If I use ModalWindow with WebPage Mode, will not have this problem.
But ModalWindow with WebPage occur in different browser page display
problems, WebPage can not get value that changed by ModalWindow's Page.

Hi,
you can consider to access to checkout order not directly with a
variable (i.e. coOrder or checkoutOrder) but using a Wicket IModel. Then
you could initialize your panel using onInitialize method, when IModel
contains the right CoOrder instance.
