A caveat, though: this approach is problematical if the form has a text input field and the user submits the form by typing return in an input field, rather than clicking a button. The problem as I understand it is that in that case you're not guaranteed which button is returned. The culprit (no surprise) is IE. So if Tom's form gets submitted by a return in a text field, and the browser is IE, he presumably wants to see the Apply button, but might see one of the reset buttons instead--not what the user intended. My approach is to use one submit button, and to make the other buttons type=button, with an onclick script to reinvoke the same controller with a button ID in vars. You'll typically check for that at the beginning of the controller. I've been using it for a cancel button, as well as some application-specific functions, and it seems to work well. > > -Thadeus > > > > > > On Sat, Feb 27, 2010 at 5:08 PM, Jonathan Lundell <jlund...@pobox.com> wrote: >> On Feb 27, 2010, at 3:00 PM, Tiago Almeida wrote: >> >> Don't know why functions reset, reset_all are not called but they reference >> a "form" variable which is not in scope?
