Slot width and subclassing

[Andre Nathan]

Hi

I was trying to figure out how to center an image in my app, and I found
the following weird behaviour:

Shoes.app do
  stack do
    p width  # ok, prints 600
  end
end

but!

class Foo < Shoes
  url '/', :index
  def index
    stack do  
      p width  # prints 0 :(
    end  
  end
end
Shoes.app

Is this a bug? Is there a workaround for this in url-enabled apps?

Thanks,
Andre
