The struts validator guide says you can only join 2 values with and or or. I'm guessing that means you either have to put in a lot more parentheses or that you can't use and or or more than once. I would first try parenthesizing everything.
Yes it evaluates pairs - so you need more parentheses as Jasper says. Theres a validwhen example in the struts-examples webapp shipped with the binary distro. Niall
