I am getting and error "Not implemented" for the line that contains:
   parent     = elem.up('li');
This only happens in IE (both 6 and 7). Works fine in Safari and FF.

elem is a valid element, I can even output it to the console.

FYI: I am using firebuglite to be able to see errors and have a debug
console in IE.

Any idea what's up? Thanks.

My guess is that it's an element, but it's not extended by Prototype in
IE.
That's a pretty typical issue.  Wrap it in an $(elem) first.

Thanks for the tip. I tried this with no avail. I did some poking
around and there is one small discrepancy between FF and IE(7). It
looks like the item is different between the two, but it is the same
element (confirmed by tagName and className).

** FIREFOX
elem: [object HTMLDivElement]
elem tagName: DIV
elem className: node node-closed over

** IE7
elem: [object]
elem tag: DIV
elem class: node node-open over

Notice the missing HTMLDivElement in IE.

What does your complete code look like?

Let me try to work up an example. The entire script is more then you
need to see.

Here is more complete idea of the code:
As I said, IE7 triggers a 'not implemented' error on the line with
parent   = $(elem).up('li');
Also, I am on proto v 1.6.0.2

  <script language="javascript">

    var TreeNav = {

      init: function(tree) {
          $(tree).observe('click',
this.toggleChildren.bindAsEventListener(this));
      }

      , toggleChildren: function(evnt) {

          elem = Event.element(evnt);

          // Is this a node?
          if (!(elem.hasClassName('node-open') ||
elem.hasClassName('node-
closed'))) return;

          evnt.stop();

          console.log('elem: '+elem);
          console.log('elem tag: '+elem.tagName);
          console.log('elem class: '+elem.className);

          parent   = $(elem).up('li');

          console.log('parent: '+parent);

          return;

      }

    };


     document.observe('dom:loaded', function(event) {
       TreeNav.init('treeav');
    });
  </script>

Try eliminating global variable declaration (i.e. "elem", "parent",
etc.)
Also, check that all id's are unique on the page.

Best,
kangax

Sorry for the late follow up. I just wanted to let any one know who
searches for this problem on here that it was what
kangax suggested. Global variable name conflicts.
