My friend John Brinkman has posted a really good list of handy form development and debugging tips. Check it out! These tips could save you a lot of time and effort. I use them all the time when I work on forms with Designer, Acrobat and LiveCycle Forms.
One other nice thing about console.println() for outputting debug information to the JavaScript Console in Acrobat is that these strings are also output to the Flash Log when you run form guides generated with LiveCycle ES Update 1 (8.2.1) using the Flash Debug Player. (The 3rd part of my MAX 2008 Tutorial series has details on how to set this up under the “Flash Log and Debug Players” section.)
