I'd like to route the user to a page not found page
can you recommend a way to do that with beamer?

Answer 1

It's best you use SimpleLocationBuilder or BeamerLocationBuilder. Those two will detect the not-found automatically, whereas a completely custom locationBuilder will not (in which case you would be just returning your custom not-found BeamLocation if all other checks fail).

For defining the not-found page, you can use either one of these properties in your BeamerDelegate:

• notFoundPage
• notFoundRedirectNamed
• notFoundRedirect (only if you're not using SimpleLocationBuilder)
