Not answering your question directly, but you might considered an alternative approach, which is to use the 'new' action for both adding and dispensing, with a parameter in the url to indicate which is required (or possibly you can already tell which action is required by examining the existing parameters). You say the two actions are very similar so this might make for less code and would solve the problem you are having with the render I think.
