bind array into polymer element attribute

[lege...@gmail.com]

This is an example http://jsbin.com/jiroz/2/edit

I'm try to bind array into polymer-list data attribute.

But it binds as string '[object Object],[object Object]'.

This not happends when polymer element is inside another polymer element, but only when polymer element is inside my custom element.

As I understand template binding should call bind method from polymer mdv that allow to bind arrays and object.

But in this case it calls original HTMLELement.bind instead.

Why this happens? Can anybody help me?

Interesting issue. I think I can help, but I will need to debug a working example to understand what is happening. Would it be possible to show a code sample?

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:
