Hi @bgschiller,

Thanks for the pull.

Changes like this which add new props to be forwarded to the <input> element are probably best implemented using the new $attrs and $listeners properties that were introduced in Vue 2.4.0.

Using those two, any attributes on <ui-textbox> which are not known props can be applied on the inner <input> element as attributes.

If you can, please update your PR to use those.

Hi @JosephusPaye,

I was wondering if there was a better way to handle this. I'll read up on those new properties and update my PR.

Thanks,
