Wicket vs Tapestry

[Adam Greene]

I was looking at Wicket Web Framework 
(http://wicket.sourceforge.net/ExampleHelloWorld.html) and realized how much it 
reminds me of Tapestry.  It says it is being released under ASL and developed 
by one of the original JFC Swing members.  Anyone else looked at this 
framework?  Does it have any ties to Tapestry in any way.  Or is it just that 
Tapestry's approach is the best and people are imitating it :-)
