Exception thrown by StackTrace.js when printStackTrace() is called

[Moboro]

If I'm just doing something wrong then my apologies up front. I didn't see a forum so I'm posting this here. I'm getting the following Exception when printStackTrace() is called:

TypeError: Object # has no method 'undef'

This happens in Chrome. In IE I see createException in the stack trace but not the above error message. What can I do about this?

@Moboro would you mind giving us a minimal test-case that reproduces the problem?

Hello eriwen,

That will take some time since this is Knockout.js code. It will be a while before I have the time to do that. In the meantime, here's a more detailed dump in case that helps:

0: "TypeError: Object # has no method 'undef'"
1: " at Object.printStackTrace.implementation.createException (http://localhost:1804/scripts/stacktrace.js?v=1.0.5:48:18)"
2: " at Object.printStackTrace.implementation.run (http://localhost:1804/scripts/stacktrace.js?v=1.0.5:35:25)"
3: " at printStackTrace (http://localhost:1804/scripts/stacktrace.js?v=1.0.5:18:62)"
4: " at null.da (http://localhost:1804/javascripts/knockout.bindings.js?v=1.0.5:344:26)"
5: " at http://localhost:1804/scripts/knockout.js?v=1.0.5:30:282"
6: " at Object.n (http://localhost:1804/scripts/knockout.js?v=1.0.5:8:296)"
7: " at Function.r.R.fn.notifySubscribers (http://localhost:1804/scripts/knockout.js?v=1.0.5:30:234)"
8: " at Function.b.G (http://localhost:1804/scripts/knockout.js?v=1.0.5:32:208)"
9: " at b as names"

The error seems to happen in the call to this.undef() in the createException() method.

@Moboro Do you use Developer Tools in Chrome? Maybe you have checked "Pause on all exceptions"?

I am getting this same error in chrome.

Run "window.printStackTrace().join('\n');" in console.

TypeError on line 48 of stacktrace.js. Gives the same error as above.
