Hey all,
In moving to edge, I noticed that the acts_as_friendly_param plugin started breaking. What should have been a 301 redirect was raising exceptions about the filter being in the wrong place.
It turns out that any around filter which renders anything persists on the filter chain, so #call_filters raises an exception because it's not an after filter. This change happened with the filters rewrite in r6649 <http://dev.rubyonrails.org/changeset/6649>\.
I just added a ticket for the bug <http://dev.rubyonrails.org/ticket/ 8341> and a patch <http://dev.rubyonrails.org/attachment/ticket/8341/ fix_rescuing_around_filters.diff> which has a good failing test case, plus my proposed fix: to pass over around filters rather than raise an exception on them.
This is blocking our usage of acts_as_friendly_param, which we're rather fond of, as it's probably the easiest way to get good SEO-happy URL structures.
Thanks!
