in latest version validation works on ff4, but not in 3.6
on devel i temporary disabled it, we can add it back when it works better
I see that you have been busy ... do I see correctly that you have even updated to a more recent version of Ace?
We can leave this open until the validation is working because I think it is a cool feature. It is just a shame that it randomly deletes lines.
