Hello Michael,
I have just completed step 34- custom controls. Here, the rating for the first time works fine but as soon as we hit the "Rate" button it gets disabled for the rest of the list also. For example, Let's say we hit the first item from the list below.
We are then directed to detail page and then we rate the product:
Now, when we have rated the product, if we go back and click some other product the rating indicator remains in the same state. 
As per my understanding, in this example we cannot save the state of this indicator for a particular product to be retrieved later(since there is no backend system available to save) but can we reset it each time we navigate to detail page after clicking the product?
I tried a couple of things but that didn't work. And in explored it says no data ( I am trying to comprehend with your above post regarding this ), so couldn't check there also.
Please guide me through this.
Thank You,
Ashutosh Hans
