[Wicket-user] If/Else component display

[Nick Heudecker]

Hi,

My app has multiple instances where, if a ListView is empty, I want to display some message to the user, like "You haven't defined any widgets yet."  The problem is this requires what I feel to be a lot of code in the Page implementation.  Is there a pattern or component that I'm missing that would make this easier? 

Thanks.
