You are witnessing Tapestry's type coercion in action. Tapestry will happily convert from null to Boolean.FALSE (see here for more info http://tapestry.apache.org/typecoercer-service.html)
If you want 3 states, (true, false and null) you will be best to have your property of type String instead of Boolean. -- View this message in context: http://tapestry.1045711.n5.nabble.com/null-value-in-Boolean-tp5713346p5713348.html Sent from the Tapestry - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
