Can you > explain why the use of an interceptor is not the right way to go about this? I'm definitely not saying it's *wrong*, I'm just saying I would question it. The idea behind interceptors (IMO only, of course!) is that they are best used to encapsulate broad functionality across the entire system (or portions of it). For example, large portions of a web app need validation flow control, type conversion of request parameters to action properties, etc. I don't know how your application is set up, but many webapps have a single "shopping-cart-like" action that handles checkout, which might involve confirmation, after which any deliverables would be returned to the user. I (again, this is just me) don't see any point to using an interceptor for this: I'd have a shopping cart (or whatever) action. Upon moving through that action I'd have a confirmation action that re-displays my "order". After that I'd have the action that actually delivers whatever it is (in your case a PDF, could be actual order submission, a thank you page, whatever). It's a very tightly-focused use-case, hence an interceptor is adding an additional layer of complexity and configuration that is just as easily (or, more likely, easier) handled with an "interim" action that handles confirmation and the next step in the process. I can't overstate enough that I have no idea how your application is designed--it's possible an interceptor *is* the best way to handle your needs, but I'm having trouble coming up with a reason why it would be better than just using another action, which would also probably eliminate the problem you're currently experiencing.
