Your example appears right and I can't remember why I left as  
static.  I will try your trick out and run all my unit tests to see  
what happens.

I'd like the jury to note, however, that to change everything all you  
had to do was alter the templates.  No code.  Hooray!  The dream is  
alive ;)

Boy, that sure looks fine...driving me crazy wondering what I was  
thinking before!
