> This only occurs when there's an overridden ExceptionReport page, and it contains a Form. Presumably, an app that redirects to another application page instead of ExceptionReport could also be affected.
> Form uses RequestGlobals.activePageName to fire an event on the active page; in an error, that is often the page that could not be loaded. This results in another exception and a 500 response to the user. Very hard to track down.
> This could be solved by changing some code to update the active page name just as the response starts to render; this would ensure that the Form is able to communicate with the correct (rendering) page.
> Also, the Form should be more capable of dealing with no active page (RequestGlobals.activePageName is null).
