Which bug it fixes?

[mark-31]

nette-live-form-validation + Bootstrap 3 + .input-group with submit button.
IMHO validation on submit is useless.

Where exactly is problem? Any side effect?

Example:

<div class="form-group">
   <div class="input-group">
      {input login-password, class => 'form-control'}
      <div class="input-group-btn">
         <button n:name="submitter-signin" class="btn btn-primary no-live-validation" type="submit">
            <i class="fa fa-sign-in"></i>
         </button>
      </div>
   </div>
</div>

Class .form-group is parental element for 2 controls.
If input:text is empty, parental element has to have class .has-error, but result is adverse, because the submitter is always positive.

@dg This PR was originally posted for nette-live-form-validation script ( contributte/live-form-validation#30 ).

Is there a reason why submit is not ignored (as this PR proposes)? Or you don't want to merge this just because it doesn't make any real change for netteForms.js itself? I haven't used nette for a while so I can't really tell what side-effects this could cause (if any).

I understand what the problem is. The same thing can happen if two inputs are together in one form-group, so a better solution is the error state only to turn on, not to turn off.
