That was actually my whole point of doing a list class from the ground up..... to get full control over the recycling of item renderers, as my project could very easily end up with 10,000+ items in a list...... Mental note to self: Do not give users that much control! :)
I'm still not sure what you mean that the component is not being used as an item renderer..... ?!?! It is exactly what I'm doing ..... a canvas component with a bunch of item renderers placed on it!
