Thanks for the test case. Polymer elements loaded at page load are not ready until the 'polymer-ready' event is fired. Here, you're registering x-test and making one before polymer-list has been registered. This means the polymer-list that's being bound in x-test's createdCallback is an unknown element and does not have the proper implementation of bind. The solution here is to wait until polymer-ready to depend on a polymer element. One more thing, you'll need to give polymer-list a height to see the content.
Here's an example: http://jsbin.com/jiroz/3 On Thu, Feb 6, 2014 at 10:56 AM, John Messerly <[email protected]> wrote: > Interesting issue.
