I’m developing on Mac OS X and stuff I’m sticking in flash is sticking  
around for two requests. For example:

/foo \<- sets flash[:notice]  
/bar \<- flash[:notice] is displayed on  
/baz \<- flash[:notice] is also displayed on  
/fubar \<- flash[:notice] is NOT displayed

Any idea why flash is persisting for two requests?

Thanks,  
Joe

flash.keep ?

Hmm, don’t think so. Unless flash defaults to two actions or something  
– I don’t see anything in /config.

Where/how do you set the flash? I know that setting the flash, and  
then redirecting, from a before\_filter had this effect a while ago  
(haven’t tested recently).

Think you’ll find a thread on rails-core about the issue. I think  
consenus was that this had to be a bug, but have no idea if it’s been  
fixed.

Instead of using flash use flash.now[:notice]

in the docs  
[http://api.rubyonrails.org/classes/ActionController/Flash/FlashHash.html#M000142](http://api.rubyonrails.org/classes/ActionController/Flash/FlashHash.html#M000142)

it says

Sets a flash that will not be available to the next action, only to the

> current.
