hi all,

using rails 1.2.3 on windows xp

i have a controller method like so:

def index stuff...
  if some_error
    flash[:notice] = "error!"

and the layout has:
  <% if flash[:notice] -%>
  <div class="flash"><%= flash[:notice] %></div>
  <% end -%>

the form for index submits via GET method.  if i cause the some_error
condition through the form, i get the flash message as expected.
however, if i immediately submit again with conditions that do not
cause some_error, i still get the flash message again.  it takes until
submitting a third time for the flash message to clear.  isn't it
supposed to clear itself after it renders the first time in the
layout?  i know i'm not setting it again because i have a debug
statement when it gets set in the controller.

ok, nevermind - i RTFM:

the method[:message] = "Hello current action"

is supposed to be used when rendering the current action;
flash[:notice] = 'some message' is to be used when using redirect_to

What you describes maps with my understanding of flash.  From
ActiveController:Flash: "Anything you place in the flash will be
exposed to the very next action and then cleared out."

I think what you want is[:notice] = "error!"
