thou shall not....use illegal ActionScript (AS) in flash forms. i'm posting this as it might save someone else time and frustration. in order to keep a lid on how wild you can get w/the super cool flash forms in cf7 there are certain AS keywords which you aren't allowed to use (in any way, shape or form):
this is all documented in Creating Forms in Macromedia Flash/Using ActionScript in Flash forms section of cfdocs. but what the docs aren't saying is that you can potentially use AS in some (to me) strange places. two of the strangest places are in alert message text and tooltips. the tooltips nearly drove me mad trying to figure out why i was getting illegal AS errors in my flash form when none of my injected AS was using any of the restricted keywords. it turns out i had a couple of buttons with the seemingly innocent "delete" word in their tooltips.
so, pay attention. if you're getting seemingly insane illegal AS errors, look to your tooltips and/or your alert messages instead of head-butting your monitor (or bombarding mike nimer with emails).
