Rating Widget and Notifiers/Observers

Question

Hello,
I am trying to figure out how to get a rating widget to update as the user clicks on spry:setrow images. I believe I need an observer and notifier but not sure what comes first. I have multiple image galleries and need to have rating rate the current image. The images are contained within an HTML Panel widget, but the rating widget is outside of said container/widget.
I want to use this to set the current row (which will give me the unique id I use to store the rating in the DB):
     var current = DATASETNAME.getCurrentRow();
This would work graet if I could get the rating widget to properly show in the HTML Panel, but I have failed at doing so.
A set of links on the left side of the page sets the dataset, and clicking the thumbnail sets the current row (of course). DO I need an observer for the link to set the ds for the above mentioned var? And then set another for the current row so I can match the image's {name} value with the rating value stored in the DB?
I think I am on the right path, but need a little direction.
Thanx!

This script should theoretically work...
var allDataSets = [dsNavigation, dsFavBlogs, dsFavCompany, dsGalleryList, dsDefaultGallery, dsCottonClubMain, dsIDSarrieriMain, dsPrimaDonnaMain, dsSawrenMain, dsSonataMain, dsValisereMain ];
var srImageRate;
for(var i = 0; i < allDataSets.length; i++){
     allDataSets[i].addObserver({
           onCurrentRowChanged: function( ds, data ){
               if( srImageRate ){
                    srImageRate.setState('initial');
                    srImageRate.destroy();
               srImageRate = new Spry.Widget.Rating("imageRating");
The allDataSets array should contain all the datasets you created. It will loop through them, and adding a observer to all of them, this observer will be called on onCurrentRowChanged.
Once the observer is called, it will reset the Spry widget.
