I'm trying to get the associated products using the method `$p->getTypeInstance(true)->getConfigurableAttributesAsArray($p)` which results in an array like this:

```
Array
(
    [0] => Array
        (
            [id] => 13
            [label] => Size
            [use_default] => 0
            [position] => 0
            [values] => Array
                (
                    [0] => Array
                        (
                            [product_super_attribute_id] => 13
                            [value_index] => 7
                            [label] => S
                            [default_label] => S
                            [store_label] => S
                            [is_percent] => 0
                            [pricing_value] => 
                            [use_default_value] => 1
                        )
[...]

```

What I'm trying to get is the product that's representing `[value_index] => 7` which is an associated simple product.

Any ideas?
