The first request is the actual request and its stack trace<http://pastebin.com/t3v2jVHK> shows the work being kicked off by the request handler. The second request stack trace <http://pastebin.com/iS2aVWY5> is actually coming from a the use of the inlines functionality in the OrderOpportunityAdmin class.
I know I could do some stack inspection using the inspect module<http://docs.python.org/library/inspect.html>, but in the past using inspect has gotten me into trouble so I try to avoid it. *Anyone have any thoughts on how I can have my __init__ tell the difference between the two times it is loaded besides using inspect*? Also, why doesn't the formset formation use the already instantiated model object?
