Working on Chrome 36 (dev)

[Jimmy Moon]

I've tested sites was build of polymer on Chrome 36.0.1941.2 dev (with Enable experimental Web Platform features). Unfortunately I got errors below and I couldn't find how to solve it. I think it's related with Native Shadow DOM
 But I'm not sure what is problems or I've missed something. How do I make workaround it?

1. Uncaught TypeError: Cannot read property 'call' of undefined patches-shadowdom-native.js:22
1. Element.webkitCreateShadowRootpatches-shadowdom-native.js:22
2. Object.defineProperties.createShadowRoot.valuepatches-shadowdom-native.js:37
3. (anonymous function)styleloader.js:78
4. (anonymous function)

These sites works well on chrome 35 beta.

webkitCreateShadowRoot showing up is suspect if you're running under the native stuff. That's the deprecated Shadow DOM implementation.

Also, what version of Polymer are you using? Do you have a jsbin that repos the issue?

I've tested some of sites on customelement.io. I was believed that they should be using newest version. But they are using 0.2.0. :)   

I tested a site after polymer updated[1] and It works well on Chrome 36 with polymer 0.2.3.  Thanks eric.

Unfortunately, many of the elements on customelements.io are out of date. Most were created by folks who wanted to experiment with Polymer but they aren't well maintained.

I know it's not the best thread to discuss it, but I'm open to ideas to fix this issue with customelements.io.

Actually, none of our project https://appmaker-integration.herokuapp.com/en-US/designer works in Canary (36). I'm still digging around, but I've found that requirejs and the Polymer() call within elements play differently together. Wrapping the Polymer() call with a require() call has worked previously, but in Chrome 36, it breaks element inheritance. Something to look out for.
