Simple Polymer 1.0 Hero Transition
Question
I am testing out neon-animated-pages to transition between two elements. I have the transition to the second element working, however, when i click to transition back to the first element the animation doesn't work. I am following what has already been done on this stackoverflow post . Thanks for your help! Here's what I have working so far:
index.html
<!DOCTYPE html>
<html>
<head>
<script src="bower_components/webcomponentsjs/webcomponents-lite.min.js"></script>
<link rel="import" href="bower_components/neon-animation/neon-animated-pages.html">

</head>
<body>
<template is="dom-bind">
<neon-animated-pages id="pages" selected="0">
<name-tag on-tag1-click="_onTag1Click">
</name-tag>
<name-tag1 on-tag-click="_onTag2Click">
</name-tag1>
</neon-animated-pages>
</template>
<script>
var scope = document.querySelector('template[is="dom-bind"]');
scope._onTag1Click = function(event) {
console.log("Square clicked");
this.$.pages.selected = 1;
};
scope._onTag2Click = function(event) {
this.$.pages.selected = 0;
};
</script>
element1.html

</template>
</dom-module>
<script>
Polymer({

_onClick: function(event) {

console.log("ELE1 "+target);
this.fire('tag1-click');
}
});

In your index.html you will need some curly braces around your _onTag1Click and _onTag2Click . That should fix it
<!DOCTYPE html>
<html>
<head>
<script src="bower_components/webcomponentsjs/webcomponents-lite.min.js"></script>
<link rel="import" href="bower_components/neon-animation/neon-animated-pages.html">
<link rel="import" href="bower_components/neon-animation/neon-animations.html">
<link rel="import" href="element1.html">
<link rel="import" href="element2.html">
</head>
<body>
<template is="dom-bind">
<neon-animated-pages id="pages" selected="0">
<name-tag on-tag1-click="{{_onTag1Click}}">
</name-tag>
<name-tag1 on-tag-click="{{_onTag2Click}}">
</name-tag1>
</neon-animated-pages>
</template>
<script>
var scope = document.querySelector('template[is="dom-bind"]');
scope._onTag1Click = function(event) {
console.log("Square clicked");
this.$.pages.selected = 1;
};
scope._onTag2Click = function(event) {
this.$.pages.selected = 0;
};
</script>

element1 defines an animation as it exits. element2 defines an animation as it enters. that is working correctly. if you want to animate back to element1 from element2, then element2 needs to define an animation 'exit', and element1 needs to define an animation 'entry'
