autocomplete - jQuery & Prototype Conflict

Question

I am using the jQuery AutoComplete plugin in an html page where I also have an accordion menu which uses prototype.

They both work perfectly separately but when I tried to implement both components in a single page I get an error that I have not been able to understand.

uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMViewCSS.getComputedStyle]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: file:///C:/Documents and Settings/Administrator/Desktop/website/js/jquery-1.2.6.pack.js :: anonymous :: line 11" data: no]

I found out the file conflicting with jQuery is 'effects.js' which is used by the accordion menu. I tried replacing this file with a newer version but newer seems to break the accordion behavior.

My guess is that the 'effects.js' file used in the accordion was modified to obtain the accordion demo output. I also tried using the overriding methods jQuery needs to avoid conflict with other libraries and that did not work.

I obtained the accordion demo from stickmanlabs.com.

And the jQuery AutoComplete can be obtained from jQuery site.

Has any one else experienced this issue?

There are two possible solutions: There was a conflict with an older version of Scriptaculous and jQuery (Scriptaculous was attempting to extend the native Array prototype incorrectly) - first try upgrading your copy of Scriptaculous.

If that does not work you will need to use noConflict() (as alluded to above). However, there's a catch. Since you're including a plugin you'll need to do the includes in a specific order, for example:

<script src="jquery.js"></script>
<script src="jquery.autocomplete.js"></script>
<script>
  jQuery.noConflict();
  jQuery(document).ready(function($){
    $("#example").autocomplete(options);
  });
</script>
<script src="prototype.js"></script>
<script src="effects.js"></script>
<script src="accordion.js"></script>

Hope this helps to clarify the situation.
