What do I do about a deprecation warning if my own code is innocent?

RuntimeError: Deprecating @session, but it’s already set to  
#\<ActionController::TestSession:0xb698eb10 @attributes={“flash”=\>{}},  
@saved\_attributes=nil, @session\_id=“”\>! Use the session= writer method  
instead of setting @session directly.  
/usr/lib/ruby/gems/1.8/gems/actionpack-  
blah blah blah  
/usr/lib/ruby/gems/1.8/gems/actionpack-1.13.1/lib/action\_controller/test\_process.rb:353:in  
`get’

I might reproduce the problem in a sample project upon request, but this  
has  
to be easy, right?

Should I grep for a @session.= and monkey-patch it? There are too  
freaking  
many of them!

Hi, you should be able to do a query/replace to change @session to  
session within your rails application.

Good luck,

If it were that easy…

…of course I have never used @session! And grep @session . -r returns  
no  
hits, so no plugin or generator has generated one.
