Forward a ResourceRequest to show the full portal

[Adrian Rodriguez]

Hello,

my intention is to process a ResourceRequest that serves a resource (A dinamically generated PDF). If something goes wrong generating this file, the whole portal with a failure message in the portlet should be rendered.

Is it possible to forward a ResourceRequest to a request that renders the complete portal? I am also considering a redirect, but I will like to be able to pass some attributes/parameters along.

I think I explained my problem clear enough. Thank you.
