  Hi Xwiki users,
 we are using Xwiki in our Intranet and I have a problem with the Navigation Panel.
 I've dragged and dropped the Navigation Panel from the Panel Wizard to the left Panel
of my site. After that I edited the Panel to my satisfaction. By the way I am using the
Default Skin with "Nature" Color Theme.
 Now to my problem. If you edit the content of the Navigation Panel you will also find the
following code:
 $xwiki.jsfx.use('js/scriptaculous/scriptaculous.js')
 $xwiki.jsfx.use('js/xwiki/accordion/accordion.js')
 <script type="text/javascript">
 document.observe('xwiki:dom:loaded', function() {
    var obj = {div:'xwikinav', no:$spacecount, height:250};
    var acc = createAccordion(obj);
 });
 </script>
 I think the "document.observe" function expands/collapses the Navigation
Fields. This function is also used to expand the Panel Wizard Fields where you can drag
and drop the panels in the Wiki administration.
 I was able to expand the fields wit Firefox 3.6.x and Internet Explorer 8.
 Yesterday I updated Firefox to version 4 and Internet Explorer to version 9. If I am
viewing the site with Firefox 4 the fields remain collapsed/closed and I can't open
them. So I can't use the Navigation Panel. Same problem with the Panel Wizard in wiki
administration. With Internet Explorer 9 and Opera 11 no problems. I can use the
Navigation Panel and the Panel Wizard without problems. I also tested Chrome 10. Same
problem as Firefox 4. With these two Browser (and these are the most used Browsers of my
users) I am not able to view and edit my Wiki correctly.
 Now where is the problem? Is that a bug in Xwiki or a bug in the javascript engine of
Firefox and Chrome? Could you give me a quick solution or workaround please?
 Best regards.
 Enzo
 
Which version of XWiki are you using? I fixed a similar bug a few weeks ago.
http://jira.xwiki.org/jira/browse/XE-845
To fix it in your instance, waiting for 3.0 to be released, you have to
edit webapps/xwiki/resources/js/scriptaculous/scriptaculous.js and add
the following condition at the start of the require function:
     require: function(libraryName) {
      if ($$("script[src$='" + libraryName.replace(/^.*\//, '') +
"']").length > 0) {
        return;
      }
