c[l][k] is not a constructor

I have been trying to remove this Firebug 开发者_运维问答Console Error from last few hours. The error which I am getting is:

c[l][k] is not a constructor
jquery-ui-1.7.1.custom.min.js (line 10)

Any siggestions would be really helpful. Thank you!

can be , duplication of the jQuery file

Well, for starters how about upgrading jquery-ui? 1.7.1 an ancient! At least go to 1.7.3 and better is 1.8.15.

Can you paste the code that triggers it?

If you don't know how to do that (or it's just too big), you start cutting your app in half. Remove half, then see if it works, if it does you know the bug was in the other half. Then you start cutting the halfs in half till you narrow it down.

It looks like the error is coming from here in the non minified version:

$.data(this, name, new $[namespace][name](this, options))._init());

• $ = c
• namespace = l
• name = k

This line means there is an error with one of your widgets. Perhaps it was designed for a different version of jQuery that you are using. I recommend upgrading both your jQuery UI and your jQuery.

Which widgets are you making use of?
