remember if you don't set the visible state (but just return true or
false depending on a other thing)
you do override the back button support a bit.
Because we can't track the visibility bit then.
Don't think it really matters but i just wanted to point that out.

I would just override isVisible() and set it to return true only when

Thanks. I'll check it out after I finish playing golf. :) I have
another associated question.
If there aren't any Pricing objects for a given Track, I want to put a
message in the page like "You don't have pricing setup yet." The
problem is that if I put that span tag in the markup:
<span wicket:id="noPricingMessage">Test</span>
And don't add the object to the page, Wicket will throw an exception.
Will calling setVisible(false) get me around this?

I'm sure this has been explained before, but it's not clear to me.
Let's say that I have a Track object, which has a List of Pricing
objects. When the user is creating a new Track, the Pricing objects
will be null, but I want to allow the user to create multiple Pricing
objects at once, using DHTML to create the new form elements.
How does Wicket handle variable numbers of form elements?
Ideally, the same page will work when editing an existing Track. Then
the question is: how do I make the current list of Pricing objects
available to the form? Use a BoundCompoundPropertyModel? A ListView?
Yep. You should use a ListView (which you can use for anything that
iterates). For each list item, create a model for your business object.
Did you check out cdapp? We'll make a release of it later this week, but
for now you could check out from CVS:
https://sourceforge.net/cvs/?group_id=134391, it's in project
wicket-contrib-examples.
The cdapp example does a very similar thing to what you want (unless I
misunderstand you;))

Thanks for your help.
