I've implemented autocomplete on an input field, but the box does not show up and firebug returns this.source is not a function. I've used autocomplete on other fields of the same page without any problems. (two textarea's).

I'm using the following code to debug, same effect if I run from script file or Firebug command line.

var fakedata = ['test1','test2','test3','test4','ietsanders'];

$(#omschrijving).autocomplete(fakedata);

running jquery 1.4.2 and jquery ui 1.8.2, both minified versions.

Does anyone have an idea how autocomplete works fine on the textareas but causes this malfunctioning on inputs?

Error & Stack trace:

this.source is not a function
