If you use classic input group in Bootstrap, error message () not show correctly.

Could you show me some live example? (URL or just simple HTML page + JS that I can just open)

<div class="col-xs-12 col-sm-8 form-group">
    <label n:name="name">{_lang.text.name}</label>
    <div class="input-group">
        <span class="input-group-addon">
            <i class="fa fa-book"></i>
        </span>
        <input n:name="name" class="form-control">
    </div>
</div>

With default settings it put the error message after <div class="input-group">...</div> which is correct. You have problems with your (Bootstrap's) CSS styles.

So what is your expected result? Where do you want to have that error message element?
