IE7 javascript error with t:panelNavigation2 resource

[Joost Schouten]

Hi,

I use a t:panelNavigation2 [1] which works great in firefox. In IE7 I get
the following javascript error: "object required"

The debugger points to the following code (I added error-->) in the resource
loaded with [2]:

startList = function() 
{
    if (document.all && document.getElementById) 
    {
        navDivRoot = document.getElementById("hNav_outer");
error-->navRoot = navDivRoot.childNodes[0];    
        for (i=0; i<navRoot.childNodes.length; i++) 
        {
            node = navRoot.childNodes[i];
            if (node.nodeName=="LI") 
            {
                node.onmouseover=function() 
                {
                    this.className+=" over";
                }
                node.onmouseout=function() 
                {
                    this.className=this.className.replace(" over", "");
                }
            }
        }
    }
}
window.onload=startList

Is this a bug or is there something wrong in my code?

Cheers,
Joost
