Easing Problem with Accordion in jQuery 1.4.2 and UI 1.8.5

Easing Problem with Accordion in jQuery 1.4.2 and UI 1.8.5

So I have am Ajax loading a set of tabs with Accordion's inside the tabs.  The tabs are working fine, but the accordion gets an easing error after the first click to switch tabs.  Firebug is throwing an error of " jQuery.easing[specialEasing || defaultEasing] is not a function" on line 5854 in jQuery 1.4.2.  has anyone ran across this?  here is my code below:
  1. <!-- ### BEGIN SCRIPT FOR TABS ### -->       
  2. <script type="text/javascript">
  3. $(document).ready(function(){
  4.     $(function() {
  5.         $("#tabs").tabs();
  6.     });
  7. <!-- ### END SCRIPT FOR TABS ### -->
  8. <!-- ### BEGIN SCRIPT FOR ACCORDIONS ### -->
  9.     $(function() {
  10.         $( "#accordion777, #accordion767, #accordion757, #accordion747, #accordion737, #accordion727, #accordion717, #accordion707").accordion({
  11.             collapsible: true
  12.         });
  13.     });
  14. });
  15. </script>
  16. <!-- ### END SCRIPT FOR ACCORDIONS ### -->
