The problem turned out to be that the JS transpiler had used the variable `w` for some bool variable in a custom element but I had declared the property `w`.   I worked around the problem by lengthening the property name to avoid any collision.  But as far as I'm aware there's no restriction on property name length so this seems like a serious bug.\r\n\r\nI'm not going to be able to provide any more than the image.  That `a.w=!1` causes everything to blow up because I have a property `w` declared as an int.\r\n\r\n![image](https://cloud.githubusercontent.com/assets/3227777/11962722/119896d4-a8b0-11e5-99f2-84449eba27d3.png)\r\n"},"comment":{"url":"https://api.github.com/repos/dart-lang/polymer-dart/issues/comments/171722258","html_url":"https://github.com/dart-lang/polymer-dart/issues/668#issuecomment-171722258","issue_url":"https://api.github.com/repos/dart-lang/polymer-dart/issues/668","id":171722258,"user":{"login":"jakemac53","id":984921,"avatar_url":"https://avatars.githubusercontent.com/u/984921?v=3","gravatar_id":"","url":"https://api.github.com/users/jakemac53","html_url":"https://github.com/jakemac53","followers_url":"https://api.github.com/users/jakemac53/followers","following_url":"https://api.github.com/users/jakemac53/following{/other_user}","gists_url":"https://api.github.com/users/jakemac53/gists{/gist_id}","starred_url":"https://api.github.com/users/jakemac53/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jakemac53/subscriptions","organizations_url":"https://api.github.com/users/jakemac53/orgs","repos_url":"https://api.github.com/users/jakemac53/repos","events_url":"https://api.github.com/users/jakemac53/events{/privacy}","received_events_url":"https://api.github.com/users/jakemac53/received_events","type":"User","site_admin":false},"created_at":"2016-01-14T17:55:31Z","updated_at":"2016-01-14T17:55:31Z","body":"@rbishop-bah is this still an issue?
