Overriding a View Function
Jamroom Developers
There are many ways to do things, what I normally do when trying to figure something out is use a server with xdebug on it and put a breakpoint where I want to be, then look back up to see what its run over.
If there's nothing in the chart of override points that works for you, how about a listener early on in the flow of things that checks if the $_post data matches a specific structure that is desired to be redirected and if it fits the case use jrCore_location() to redirect to where you want to go. It would cause a page refresh, but would probably not be noticed by the user who is waiting for a page refresh at that point anyhow.
