How to use animate-initial-selection

[BartKoppelmans]

Hello,

I am not sure how to use animate-initial-selection in the neon-animated-pages element.

I have the following setup:

    <neon-animated-pages id="pages" selected="0" animate-initial-selection>

      <letter-holder-page></letter-holder-page>

      <letter-detail-page></letter-detail-page>

    </neon-animated-pages>

My letter-holder-page and letter-detail-page share an element and have hero-animations to share the element. Is my use of animate-initial-selection correct? And if so, why do I get an error that says:

Uncaught TypeError: Cannot read property 'getAnimationConfig' of undefined

Hey Bart,

I think you're using that property right (though i haven't used it myself). But the error you're seeing about getAnimationConfig probably indicates that <letter-holder-page> doesn't implement Polymer.NeonAnimatableBehavior Or one of the other behaviors that expose animationConfig. Can you verify that?

Hey Dan,

It does, it implements Polymer.NeonSharedElementAnimatableBehavior. Everything is working correctly without the animate-initial-selection. With, however, it doesn't.
