Compatibility with product bundles

Hi

The plugin works great with simple products but it doesn’t work with the ‘product bundles’ extension. It seems as if product bundles uses it’s own code to display that a bundle is out of stock rather than relying on woocommerce. I contacted woothemes support and they responded with the following but I have no clue what they actually want me to do with this code. Can you be of any assistance?

“Use $bundle->all_items_in_stock() in combination with is_in_stock(). The latter one is restricted to the bundle-level stock status, while the former one is based on the contents’ stock status. Alternatively, you could use get_availability for the same purpose.”
