> It would be nice if there was a way pages could define an event handler that would be notified in the event of an exception while processing the page; it should be passed the exception and some indicator (an enum) of where the exception occured.  This would allow a way for individual pages to handle certain exceptions in a specific way.
> A particular use case for this would be handling the case where parameters can not be coerced when invoking an activate event handler method, but there's quite likely many others.
