`func.apply` in `_.once` is breaking my asynchronous validations about judge HOT 3 CLOSED

So, I dropped in the underscore-rails gem and ... this error cropped up again but on a different method (_.before), same code (memo = func.apply(this, arguments);). Looks like I'll need to take this up with the Underscore repository. If you've got any input I'd love to hear it but I'd also understand if you wanted to close this issue since it doesn't look to be an actual issue on Judge.

Yeah, looks like it may be an issue with the coffeescript or dependency order. Unfortunately I'm not great with coffeescript so I'm not much help here.

Since this isn't an issue with the gem I'm going to close this one out.

After posting over in the Underscore repo it was pointed out to me that I wasn't properly creating the callbacks as methods. I've been staring at this code by myself for so long I'd totally missed it. In case anyone needs to know, this is the fix that did it.

q = judge.validate element,
      valid: (element)=>
        @valid element, deferred
      invalid: (element)=>
        @invalid element, deferred
