loosing the plot somewhere with the following cfc, I would really appreciate
some expert input from someone (Sean where art thou)..
I believe I need to lock any access to the object as its in the server
scope, not sure yet whether it gives better performance creating the object
only once in the server and lock access to it, or recreate the object every
time and not having to lock access to it, I believe its the first one.
I think I am losing the plot when we get to
request.result.objError.fnConstruct( request.result );
request.result.objError.fnDisplay( request.result );
But I can't really tell you why, but I'm pretty sure its not a good thing
having to pass itself back with request.result
Hope someone's still awake..
