Diasabling user input during skill choice

Since there is bug in skill choice that when user failed to select a choice and type something in user text area, it will not giving failure message. I want to disable user input during an choice skill event for user. so that he has to select any of choice and not typing anything user input.

Is there any update on this topic? Would be nice to hear about.

AFAIK there is no way to disable user input.
