polymer focus() on <paper-input> or <core-input> element

Question

Is there a way to focus core-input or paper-input element?

What I want to achieve is: set cursor to input element so user can start typing.

This way he will not be forced to click on element before writing.

Answer 1

core-input is missing focus()/blur() API, this is essentially a bug.

For now you can do this:

<reference to a core/paper-input>.$.input.focus();
