Autocomplete: Microsoft JScript runtime error: Object doesn't support this property or method

Autocomplete: Microsoft JScript runtime error: Object doesn't support this property or method

Hi All,

I tried using the example as is given on the  http://jqueryui.com/demos/autocomplete/#remote-jsonp link. It always gives me an error "Microsoft JScript runtime error: Object doesn't support this property or method".
I tried this example on IE 7 and Chrome web browsers.

I'm using jQuery 1.4.1.min.js, jquery-ui.min.js, jquery.ui.core.js, jquery.ui.autocomplete.js, jquery.ui.position.js and jquery.ui.widget.js

I examined and found the issue while using the sample code with and without master page and found that the problem is with masterpage.

Please suggest some solution for the said problem.


Thanks
