Exposing knowing when an animation on an element is complete through some interface on the element would solve it, and seems more generally useful. The only thing I'd add is that there should also be a way to know if the element is currently animating or has a pending animation. Otherwise, in this case, I might be stuck waiting on animations that'll never happen. > > > On Mon, Jul 7, 2014 at 4:11 PM, 'Steve Orvell' via Polymer < > [email protected]> wrote: > >> There's not a good way to do this currently.
