Polymer setup Instructions resulted in blank screen

[eseidel]

I followed the instructions on:
http://www.polymer-project.org/getting-the-code.html

Including installing bower (v1.2.8) npm (1.3.24) and the polymer components:
bower install --save Polymer/polymer-elements
bower install --save Polymer/polymer-ui-elements

However when I follow the instructions to "test my environment" [http://www.polymer-project.org/getting-the-code.html#testbower] by creating an index.html pasting in the referenced HTML, and then running a local server "python -m SimpleHTTPServer". Navigating to http://0.0.0.0:8000, all I get is a blank screen. "OneTwoThreeFourFive" appears briefly (before the script runs) and then disappears in 32.0.1700.107 (Official Build 248368). No messages/exceptions in the chrome console. I tried in FF 27.0.1 and see "OneTwoThreeFourFive" and no messages in the console either. Neither seems to show the intended tab-strip UI.

It appears that whatever version of polymer I pulled is unstable/not-working?

wfm on chrome canary, maybe relies on > 32 chrome right now?

Works for me on both Chrome stable (32.0.1700.107) and Firefox 27 (both on
Windows). What OS are you using?

Re: Chrome, do you have any experimental flags turned on?

Re: Firefox, iirc version 23 is stale and Gecko has changed already. Try
with the latest version?

Fwiw, version numbers are embedded in polymer/polymer.js and
platform/platform.js between the license text and the code; you should have
version 0.2.0 of both.

Crap. Looks like I have experimental-web-platform-features enabled for Stable on my personal machine. No clue when I turned that on.

Disabled --experimental-web-paltform-features and now it works fine in M32. Still broken in FF 27.0.1 which means I can't actually use this for the website I'm working on, but at least I can play with it in Chrome. :)

Thanks. Sorry for the noise.

grep version bower_components/platform/platform.js bower_components/polymer/polymer.js
bower_components/platform/platform.js:// @Version: 0.2.0
bower_components/polymer/polymer.js:// @Version: 0.2.0

[eseidel]

Now it's working fine in FF 27.0.1. So odd. I must have just been confused earlier. Again, apologies for the noise.

No worries about noise, we want/need to know where there are rough edges. Thanks for all the detailed info.
