Right, I have pretty much all of my validations working now... and here's the word you're waiting for... but, I am having a problem with fields that are already visible when the rest of the layout changes.
Basically, one of the options above the field with the problem is being changed, which makes the layout above that field change. This is triggering the validate event.
This wouldn't stop anyone using my form, but it is an annoyance.
Anyone able to help?
