autocomplete not filtering based on input

autocomplete not filtering based on input

i'm attempting to integrate jquery/jqueryui into a spring 3.0.3 app.

i have 2 autocomplete widgets on my jsp page.  the first uses a source of local defined array, like the documentation example.  this widget works as expected.  items in the suggested list are filtered.

  1.     $("input#autocompleteDemo").autocomplete({
  2.             source: ["c++", "java", "php", "coldfusion", "javascript", "asp", "ruby"]
  3.         });

in the second widget, i've set the source to retrieve the array of suggested values through a url.  when typing in the autocomplete widget, ALL values returned are displayed, regardless of what is typed.  The autocomplete is not filtering the suggested values.  in the UI, it looks like the list is refreshed when typing (list slightly flashes).

  1. $("input#autocomplete").autocomplete({
  2.             source: "/autocompleteStuff.htm",
  3.             minLength: 0,
  4.             delay: 70
  5.         });

  using firebug, i can see the response:
  1. ["apple","orange","grape","watermellon","strawberry","mango","pinapple","blueberry","cherry","raspberry"]
what am i missing?!?
