Stop on ognl, prop is not powerful.
Creating java method
public boolean isSufficientPlayers() { return playersOnline > 100; }
instead
ognl:playersOnline > 100
is not good idea
1. You move presentation in to java code
2. You lost control on viewable presentation code, 100 or 50 or 1000
palyersOnline...
3. Less usability
4. Don't wait future release of tapestry, maybe it will be in 2010 or
2011 :), but feature have needed yesterday
