We are using polymer for our some of the components in our hybrid app. When I upgrade polymer 0.5 to 1.0 I kept seeing this error message:
polymer-micro.html:401 Uncaught TypeError: this.mixin is not a function

I have no idea what I did wrong. The components are working fine in the demo index files. When I load the component to my project, even just polymer was broken

Offending line here: https://github.com/Polymer/polymer/blob/v1.0.0/polymer-micro.html#L401

Reproduced here: http://jsbin.com/rapoci/edit?html,console,output

Fail conditions:

  • Use polymer-micro.html
  • Include a behavior that has hostAttributes

Root cause: _addHostAttributes calls this.mixin, which is defined in utils.html which is only included in polymer.html (standard layer). mixin should be moved to be included in polymer-micro.html
