I have an interesting dilemma! I created an example that WORKS based on
Alan's code below. The page is at:
http://www.accollarts.net/example/example3
It has page elements <[code-init]> and <[tree_snippet]>. To be able to try
out some new things with this code, I created a new page with the exact same
code. But guess what? IT DOESN'T WORK! This page is at:
http://www.accollarts.net/example/example4
I don't understand what may be happening. The actual page displays properly,
but when I click on a link, I get an error "The requested URL was not found
on this server". This is strange, because I thought that I read that
elements with the same name overwrite previous elements. Is this a bug?
