Polymer/Paper path parsing issue.

[ncooper123]

I am using emcee 1.0.7 with polymer 0.4.1 and paper and I'm running into the following error with Rails 4.1.1.:

It appears emcee may be mis-parsing the {{..}} within the paper-shadow/paper-button source. Any suggestions?

This definitely looks like a bug in Emcee, and you're definitely right about the {{ ... }}. Do you have an example repo I can use to look into this?

Here's a quick rails app I rigged up:

The problem seems to lie with the <paper-icon-button icon="menu"></paper-icon-button> tag

Cheers.

This should be fixed in release 1.0.8. After updating to the new version, you may have to clean out the old assets in any Rails projects that use this. You can do that with rake assets:clean && rake tmp:clear from the project root.

Here's a screenshot of your test app working:

Works like a charm now. Thanks!
