Rails spinoffs - Oct 2005 - sorting error "Error: item.id has no properties"

I''ve got some sorting working now, but when the page loads and when I  
drag, I keep getting this error:

"Error: item.id has no properties"

My <ul> and <li> elements all have ids. Do child elements all need
ids?

Here''s the code from dragdrop.js where the error is being thrown ( a  
few lines from the bottom of the file, line 501--HEAD version)

serialize: function(element) {
     element = $(element);
     var sortableOptions = this.options(element);
     var options = Object.extend({
       tag:  sortableOptions.tag,
       only: sortableOptions.only,
       name: element.id
     }, arguments[1] || {});
     return $A(element.childNodes).collect( function(item) {
       return (encodeURIComponent(options.name) + "[]=" +
               encodeURIComponent(item.id.split("_")[1]));          
<---------error occurs here!
     }).join("&");
   }

Any ideas?

Thanks,

Jamie

turns out that having some commented code (an old table row) inside  
the list element was the problem. Go figure.

This should be fixed in HEAD.
