has-error with input-group

[afattahi54]

When applying the has-error with input-group the border-right-color will not apply

It seems that we must put below css in order to have error color show in the right border too
.has-error .input-group-addon:first-child{
color:#ec0000 !important;
border-color:#ec0000;
background-color:#f2dede
}

The bootstrap-rtl has below selector which prevents correct color on right border:
.input-group-addon:first-child{
border-right:1px solid #ccc;
border-left:0
}
