Before the 6.1 upgrade the variables scope was broken, being directely accessible from outside the CFC (a common workaround was to use the "unnamed" scope instead).

Same for the CFML/HTML version of the Pet Market. Actually, you can even spot quite a bunch of missing "var" inside methods there. It's a shame, since there are other aspects of it that I fund interesting. ---------------------------- Massimo Foti DW tools: http://www.massimocorner.com CF tools: http://www.olimpo.ch/tmt/ ---------------------------- ---------------------------------------------------------- You are subscribed to cfcdev.
