Dependencies for Hybrid Element and not able to upgrade to class-based elements

[Laurent Besson]

Hi,

I would like to upgrade my custom component to class-based elements on an hybrid poject.

My project run actually with Polymer 1.7.1 and I would like to switch to a Hybrid project having Polymer 1.7.1 and have Polymer 2.0.0-rc.7 in parallel. I followed this guide https://www.polymer-project.org/2.0/docs/devguide/hybrid-elements.

I tried to update too update my following  dependencies:

"paper-button": "PolymerElements/paper-button#2.0-preview",
"paper-input": "PolymerElements/paper-input#2.0-preview",
"paper-icon-button": "PolymerElements/paper-icon-button#2.0-preview",
"paper-card": "PolymerElements/paper-card#2.0-preview",
"paper-toggle-button": "PolymerElements/paper-toggle-button#2.0-preview",
"paper-tooltip": "PolymerElements/paper-tooltip#2.0-preview",
"paper-material": "PolymerElements/paper-material#2.0-preview",
"paper-spinner": "PolymerElements/paper-spinner#2.0-preview",
"paper-item": "PolymerElements/paper-item#2.0-preview",
"paper-dialog": "PolymerElements/paper-dialog#2.0-preview",
"paper-checkbox": "PolymerElements/paper-checkbox#2.0-preview",
"paper-toolbar": "PolymerElements/paper-toolbar#2.0-preview". A the end I have polymer 1.9.1 in my bower folder instead of 2.0.0 rc and so I do not have polymer.element.html which is required for class-based elements. class MyElement extends Polymer.Element Do you have a explanation or a solution for this issue? Thanks. Laurent

Try using github urls instead element name (
https://github.com/PolymerElements/paper-toggle-button.git#2.0-preview). As tags for  2.0-preview are not yet created, bower might not be able to find the required tag/branch.

One thing you'll need to do (that's missing from the current version of the guide) is remove your existing bower_components folder to make sure it doesn't try to resolve packages against stuff you already have installed.
