Possible problem with dependencies

[mikebevz]

Hi,

I've got the following setup

-Gemfile

gem 'polymer-rails' gem 'polymer-core-rails' gem 'polymer-paper-rails'

-components/application.html.erb

//= require polymer/polymer //= require paper-button/paper-button //= require core-animated-pages/core-animated-pages

-javascripts/application.js

//= require polymer/platform //= require jquery //= require jquery_ujs //= require turbolinks //= require_tree .

• layout/application.html.erb

true %> true %> - in view/home/index.html.erb

<paper-button label="raised button" raisedButton>

---

In JS console I"ve got an error:

Uncaught NotSupportedError: Failed to execute 'registerElement' on 'Document': Registration failed for type 'core-meta'. A type with that name is already registered. polymer.js:12 f.registerPrototype polymer.js:12 f.register polymer.js:12 d._register polymer.js:13 e.flush polymer.js:12 e.ready polymer.js:12 e.check polymer.js:12 e.go polymer.js:12 d.registerWhenReady polymer.js:13 (anonymous function) polymer.js:13 d platform.js?body=1:16 e platform.js?body=1:16 (anonymous function) platform.js?body=1:16 g platform.js?body=1:16 b.resolve platform.js?body=1:16 b.fetch platform.js?body=1:16 b.handleXhr platform.js?body=1:16

Any idea what it could be? I tried different combinations but it seems like 'polymer-core-rails' and 'polymer-paper-rails' do not like each other.

You cna download Rails app with this problem here - https://www.dropbox.com/s/7aqi4pho5s230o8/polycalc.zip
