ReferenceError: PathObserver is not defined when loading in node-webkit

[cadorn]

I am trying to load polymer-all/polymer/polymer.js (stable v0.0.20130802 and master] in node-webkit version v0.6.3 and am getting the following errors:

Uncaught ReferenceError: PathObserver is not defined template_element.js:508

(anonymous function) template_element.js:550

It looks like the node.js global namespace is colliding with how MDV boots itself. All the MDV modules are wrapped in an IIFE that uses global as the loading scope

(function(global) {
...
})(typeof global !== 'undefined' ? global : this);

Since this is really an MDV issue, I'll post that bug over there.

That line was added by Sam Duvall here: googlearchive/observe-js#17

Any chance I can get someone to craft a pull request which fixes this correctly for all node contexts?

Also, note that ChangeSummary has been renamed to ObserveJS and moved into the Polymer organization here: https://github.com/Polymer/ObserveJS

I'm having this issue here, it actually starts with not finding ArraySplice... any hint on how to fix that? I really wanna use polymer with node-webkit...
