undefined method `span_size' for #<Arbre::HTML::TextNode:0xaf250ddc>

activeadmin (1.0.0.pre)

When I have 2 'columns' on same page, rails throws this message:
undefined method `span_size' for #Arbre::HTML::TextNode:0xaf250ddc

Here's an example:

ActiveAdmin.register_page "Dashboard" do
    menu :priority => 1, :label => proc{ I18n.t("active_admin.dashboard") }

    content :title => proc{ I18n.t("active_admin.dashboard") } do
        columns do

        end
        columns do 

        end
    end
end

First, this is the wrong repository 🐱. This should be at https://github.com/gregbell/active_admin

Second, there should only be one columns call, as illustrated in the docs.

The demo have 2 twos columns...
It is wrong, no?

Ah, you're right.

This error turns out to have nothing to do with using columns twice. Instead, it occurs when you call columns and don't provide any column calls for it to use.

# causes the error
content do
  columns do
  end
end

# doesn't
content do
  columns do
    column {}
  end
end

My application have two 'columns' with more of 1 column inside and show the
same error.

I am using rails 4.0.2.

The demo version is different of the repository?

Thanks
