[Radiant] any way to dynamically populate <r:random>?

[john muhl]

I have to admit that rspec is still a bit intimidating, so I'm not  
sure this is exactly the sort of spec you were looking for. Feel free  
to point out everything that's wrong here and I'll try again.

      page.should render("<r:random> <r:option>1</r:option>  
<r:option>2</r:option> <r:option>3</r:option> </r:random>").matching(/ 
^(1|2|3)$/)
    end

r:children:each></r:random>').matching(/^(Child|Child\ 2|Child\ 3)$/)

    it '<r:comment> should render nothing it contains' do
      page.should render('just a <r:comment>small </ 
r:comment>test').as('just a test')

The failure is:

     expected "<r:random><r:children:each><r:option><r:title /></ 
r:option></r:children:each></r:random>"
     to render and match /^(Child|Child\ 2|Child\ 3)$/, but got "Parent"
