Rails - Jan 2011 - Flash :notice in redirect_to not working in some cases?

Rails3.0.3, Controller:Method update:
  
1. Redirect to Show, flash is shown, works
      format.html { 
           redirect_to(@article, :notice => ''Article was
successfully
saved.'')
        }

2- Redirect to Edit, flash is shown, works
        format.html { 
          flash[:notice] = ''Article was successfully saved.''
          redirect_to(:action => ''edit'') 
        }

3. Redirect to Edit, flash is NOT shown
        format.html { 
          redirect_to(:action => ''edit'', :notice =>
''Article was
successfully saved.'') 
        }

The flash is in application.html.erb:
<section id="content">    
        
        <section id="flash">
            <% flash.each do |key, value| %>
                <div class="flash <%= key %>"><%= value
%></div>
              <% end %>
        </section>
            
        <%= yield %>
    </section>    

Can someone explain this behaviour to me?

In the third case, rails thinks that :notice is part of the routing
options  - you can probably see that the url redirected to has ?
notice=... on it. Ruby can''t know that the first bit is for the
routing options has and that the second bit is for the other options
hash. On the other hand, in the first case it is unambiguous
