I don't know exactly what you're trying to accomplish from the 
information you provided, but this approach doesn't "feel" right to me.

I would put the content of the page/dialog into a partial. I'm going to 
assume that your dialog version will be rendered by an AJAX call.

In that case I would use respond_to to determine which layout to render:

respond_to do |format|
  format.html # Render page with default layout
  format.js # Render the dialog version
end

In case you're not rendering the "dialog" version with AJAX then you 
might want to use a custom MIME type to render the alternate layout:

respond_to do |format|
  format.html # Render page with default layout
  format.dlog # Render the dialog version as HTML using custom format 
type
end

I'm not sure how you will be determining which layout to use, but if you 
absolutely had to store this in a variable you would need an instance 
variable on your controller.

However, as I mentioned before moving the decision into the request 
seems like the better approach.
