rails 3 routes

Hi, I'm using the 2.5 EAP with rails 3. I'm using both :namespace and :scope in my routes.rb, for nice URLs. RubyMine can't autocomplete such routes and complains that the method doesn't exists.
rake routes
displays them all correctly, why don't RM? When we'll it be fully supported? Btw, I love your product and mean no offence.
