[Moo] Help with Request.HTML in 1.4.5

[mr smith]

I've had to migrate a project from 1.2.5 to 1.4.5 and for some reason the 
following function no longer works:

                        var req = new Request.HTML({
    onSuccess: function(responseTree, responseElements, responseHTML) {   
    
var myElement = responseElements.filter('#' + subnavID);
        var myContent = myElement.get('html');
        textHolder.set('html', myContent); 
    }
}).get('text/' + togglerID + '.html');


(The variables togglerID and subnavID are just identifiers from an 
accordion navigation.  The function is designed to grab the html in a div 
(among several) from a text file, depending on the navigation element 
clicked, and put it into textHolder.  In 1.2.5 it worked perfectly, but in 
1.4.5 it just displays [object Object].  Any ideas on how to update this 
function to work with 1.4.5 would be so appreciated.   Thanks!
