[Radiant] <r:random> and page children

[Sean Cribbs]

I've been following this thread, but haven't replied yet.  The problem may
be a tag scoping issue, and maybe a custom tag is in need here.

tag "children:random" do |tag|
  children = tag.locals.children
  if children.size > 0
    index = rand(children.size)
    tag.locals.page = children[index]
    tag.expand
  end
end

Then in your page, write

<r:children:random /><r:title /></r:children:random>

or just
<r:children:random:title />

This will only select one child page, mind you, and would need to be
modified to select more than one.

Cheers,
