Uncaught TypeError: Cannot call method 'hasOwnProperty' of undefined

[ramontayag]

I'm new to backbone, but this doesn't look like it should be happening. I have a session model:

class OLBT.Models.Session extends Backbone.Model
  name: 'model'
  urlRoot: 'devise/sessions'
  defaults:
    sessionId: ''
    userId: ''
    email: ''

When I create a new model, session = new OLBT.Models.Session(), I get this error: Uncaught TypeError: Cannot call method 'hasOwnProperty' of undefined. Looks like maybeUnwrap is choking when no args are passed in. Not sure what this does yet, but checking if typeof(args) != 'undefined' before continuing fixes it.

Am I doing something wrong, or is this a valid issue?
