Migration the hard way

[Vincent Uribe]

Hi!

I've been developping a webapp since january and kept going with Polymer 0.5 as the 0.8 was not final enough for my tastes. I started migrating to the 0.9 today and have been somewhat battling with this error:

Uncaught TypeError: Polymer.dom is not a function

Uncaught TypeError: Cannot read property 'instanceCount' of undefined

Uncaught NotSupportedError: Failed to execute 'registerElement' on 'Document': Registration failed for type 'paper-ripple'. A type with that name is already registered.

This is my bower.json:

  "dependencies": {

    "polymer": "Polymer/polymer",

    "iron-ajax": "PolymerElements/iron-ajax",

    "iron-autogrow-textarea": "PolymerElements/iron-autogrow-textarea",

    "iron-icon": "PolymerElements/iron-icon",

    "iron-a11y-keys-behavior": "PolymerElements/iron-a11y-keys-behavior",

    "iron-a11y-keys": "PolymerElements/iron-a11y-keys",

    "iron-input": "PolymerElements/iron-input",

    "iron-signals": "PolymerElements/iron-signals",

    "iron-icons": "PolymerElements/iron-icons",

    "iron-collapse": "PolymerElements/iron-collapse",

    "iron-flex-layout": "PolymerElements/iron-flex-layout",

    "iron-fit-behavior": "PolymerElements/iron-fit-behavior",

    "paper-button": "PolymerElements/paper-button",

    "paper-toolbar": "PolymerElements/paper-toolbar",

    "paper-tabs": "PolymerElements/paper-tabs",

    "paper-toast": "PolymerElements/paper-toast",

    "paper-menu": "PolymerElements/paper-menu",

    "paper-item": "PolymerElements/paper-item",

    "paper-header-panel": "PolymerElements/paper-header-panel",

    "paper-icon-button": "PolymerElements/paper-icon-button",

    "paper-drawer-panel": "PolymerElements/paper-drawer-panel",

    "paper-checkbox": "PolymerElements/paper-checkbox",

    "layout": "Polymer/layout",

    "neon-animation": "PolymerElements/neon-animation"

  },

  "resolutions": {

    "polymer": "v0.9.0-rc.1",

    "webcomponentsjs": "^0.6.0"

  }

Am I doing something wrong?

Thanks in advance.

You should be installing Polymer 0.9.0, not 0.9.0-rc.1.

Other than that, it's hard to know what the problem is without code. "Polymer.dom is not a function" sounds like you might be importing the 0.5 version of Polymer. Try logging Polymer.version as a sanity check?
