I moved my project from rails 2.0 to 2.1 and map.root stop working:  
It means if I have e.g:  
map.root :controller =\> ‘sessions’, :action =\> ‘new’  
it not working,  
but when I try do this  
map.new\_session :controller =\> ‘sessions’, :action =\> ‘new’  
map.root :new\_session  
I have error:  
/usr/lib/ruby/gems/1.8/gems/actionpack-2.1.0/lib/action\_controller/routing/builder.rb:197:in  
`build’: Illegal route: the :controller must be specified!  
(ArgumentError)

any ideas?

Sorry:

it works: map.root :controller =\> ‘sessions’, :action =\> ‘new’

but this:

map.new\_session :controller =\> ‘sessions’, :action =\> ‘new’  
map.root :new\_session

not working, but in rails 2.1 it should…

any ideas?
