Redraw control that expects some argument in render

Hi there.
I understand this is not possible, although I want to understand why and if there's a plan to support this.

Let's imagine this piece of code:

{foreach $products as $product}
<h2>Product: {$product->name}</h2>
Buy: {control buyButton:small, product => $product}
{/foreach}

If user clicks on the button, I want to check if there's any product left in the stock and based on that information I want to show how many pieces there are left. Then I'd expect to have component's handler similar to this:

	public function handleAddToBasket($id)
	{
		$product = $this->presenter->db->table('items')->get($id); // Get the product from DB
		$this->presenter->cart->addProduct($id, $product); // ++ product to cart
		$this->presenter->getComponent('basket')->redrawControl(); // Redraw the basket in page's header
		$this->redrawControl('buyButton', TRUE, $id); // Redraw THE buy button
	}

If I simply call $this->redrawControl(‘buyButton’) I'm getting error “Missing expected parameter for render()” which I understand.

So, the question is, is it possible to implement something like this?

BTW. I've tried the snippetArea without luck. The component buyButton needs the ID and the snippetArea does not help with this.

Thanks.
