no method '_bindRoutes' in Chrome 22.0.1201.0 dev

[chuangbo]

In the lastest chrome dev 22.0.1201.0, Backbone test suite have a global failure.

Backbone.Events: global failure (1, 0, 1) Rerun

Uncaught TypeError: Object function (attributes, options) {
    var defaults;
    attributes || (attributes = {});
    if (options && options.parse) attributes = this.parse(attributes);
    if (defaults = getValue(this, 'defaults')) {
      attributes = _.extend({}, defaults, attributes);
    }
    if (options && options.collection) this.collection = options.collection;
    this.attributes = {};
    this._escapedAttributes = {};
    this.cid = _.uniqueId('c');
    this.changed = {};
    this._silent = {};
    this._pending = {};
    this.set(attributes, {silent: true});
    // Reset change tracking.
    this.changed = {};
    this._silent = {};
    this._pending = {};
    this._previousAttributes = _.clone(this.attributes);
    this.initialize.apply(this, arguments);
  } has no method '_bindRoutes', http://documentcloud.github.com/backbone/backbone.js:871

Is it a bug of Chrome?

Hey @chuangbo! I'm fairly certain that this is an issue with the latest Chrome. #1475 has more details, including the Chromium bug, which seems to have been fixed already.

Many thanks @braddunbar !

Seeing this in Android and mobile safari, too...

Here are the user agent strings of the offending browsers I've noticed:

Mozilla/5.0 (Linux; U; Android 4.1.1; hr-hr; Build/JRO03C) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Safari/534.30
Mozilla/5.0 (Linux; U; Android 4.0.4; en-us; PMP5580C Build/IMM76I) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Safari/534.30

Is there any fix for these users?

@adambom do you get the same exact error? I tried my apps with a few Android device and haven't had any issue so far. Would you mind paste the stack trace here?

[adambom]

Yeah basically. I'm not personally seeing this, but it's being recorded and sent to a log using window.onerror. I'm also seeing it for Chrome 22.0.1201.0. I guess some people are still running that version.

My backbone version is 1.0.0.

Unfortunately, window.onerror doesn't capture stack traces, but here's the error (sorry for the minified code):

TypeError: Object function (a,b){var c,d=a||{};b||(b={});this.cid=i.uniqueId("c");this.attributes={};i.extend(this,i.pick(b,p));b.parse&&
(d=this.parse(d,b)||{});if(c=i.result(this,"defaults"))d=i.defaults({},d,c);this.set(d,b);this.changed={};this.initialize.apply(this,arguments)} has no method '_bindRoutes'
  File "http://chat.messageme.com/app.min.js", line 294

And here is the beautified version:

function (a, b) {
    var c, d = a || {};
    b || (b = {});
    this.cid = i.uniqueId("c");
    this.attributes = {};
    i.extend(this, i.pick(b, p));
    b.parse &&
        (d = this.parse(d, b) || {});
    if (c = i.result(this, "defaults")) d = i.defaults({}, d, c);
    this.set(d, b);
    this.changed = {};
    this.initialize.apply(this, arguments)
}
