A readonly, radio button on a spawned page has a value, but is not displaying it.

I have a top/cover page with some basic demographic fields whose values are going to be repeated as read-only on subsequent pages.

One of the fields is a radio button with the choices LEFT or RIGHT.

The subsequent pages are all unique, hidden templates that are spawned on demand via

      this.getTemplate("Page2").spawn(1,false);

      this.getTemplate("Page3").spawn(2,false);

      this.getTemplate("Page4").spawn(3,false);

The text fields and date fields that are on the top/cover page populate into their read-only counterparts on the tops of the new pages.

And, the VALUE of the radio-button successfully assigns to it's read-only counterparts (programmatically confirmed it accepted the choice value), but the radio button is NOT DISPLAYING the tick mark.  This was not the behavior before I turned the pages into templates.  When I was developing the pages the code worked like a champ.  And, even now if i hidden=false on the template pages, the code works fine and the LEFT / RIGHT choices on the subsequent pages behave as expected. The problem started after I changed them to templates, then started spawning the pages open.

What is going on here?  I suspect it is somewhere in the form field vs. form object, but I'm perplexed.

Help?!
