Rails - Mar 2005 - Problems with 0.11.0 - flash.rb?

Having updated to 0.11.0, (though by uninstalling and then installing  
instead of using "gem update", because that didn''t seem to
actually
make my app aware of the new libraries) I find that my app is now  
broken. When attempting to call the index action of my "topic"  
controller, I get the following error:
> NoMethodError in  Topic#index
> undefined method `discard'' for {}:Hash
with the following framework trace:

I''m sort of imagining this not really being a problem with the code in
"flash.rb", and instead with something that calls it, but of course I
have no real idea about that.

Anyway, please help! If it is bad form to post things like this on the  
mailing list, I apologize.


Thanks,

Yeah, I hid it at the end of the announcement:

"You shouldn’t need to change any code. You will need to clear out all  
your sessions, though, because of the Flash module upgrade!"

(How embarrassing! I just needed to clear my session to fix this. 
Terribly sorry, everyone.)

Maybe you should update the post telling how to do it? (just to be 
super clear)
