One weekend later and I'm working on this again. Here's my situation:
page
- browse panel
- cart panel
- modal window
- - edit item form (inside the modal window)
I have an ajax submit button in the EditItemForm. I need to call
public void onSubmit(AjaxRequestTarget target, Form f) {
target.addComponent(theCartPanel);
ModalWindow.close(target);
}
My problem is: how do I get access to the cart panel from within the
form in the modal window? Here's what I've come up with, and
everything feels a bit ugly:
1. I can get the cart from the session and have the cart fetch the
cart panel -- ugh, the cart (business object) shouldn't know about a
UI widget.
2. I can pass the cart panel in as my model object
3. I could put the cart panel in the session (or my own ThreadLocal)
4. I could crawl my way back up
findParent(ProductPanel.class).visitChildren(IVisitorThatHandlesTargetAddComponent)
Any suggestions would be entirely welcome.
Thanks,
Scott

Power is not a means, it is an end. One does not establish a
dictatorship in order to safeguard a revolution; one makes the
revolution in order to establish the dictatorship. The object of
persecution is persecution. The object of torture is torture. The
object of power is power. -- George Orwell, 1984
