So, how do I get this HappySession to work? I've tried several things but 
there's a cache that must (occasionally) be cleared and the author 
recommends the error_type trick, which doesn't work for me:

<dtml-if expr="URL[-(_.len('_frame')):]=='_frame'">
  <dtml-try>
   <dtml-call "SESSION.set('select_blueline_temp',select_blueline(_.None,_))">
  <dtml-except>
   <dtml-if expr="URL[-(_.len('_frame')):]=='index_frame'">
    <dtml-return index2_frame>
   <dtml-else>
    <dtml-return index_frame>
   </dtml-if>
  </dtml-try>
</dtml-if>

or, alternatively...

<dtml-comment>
<dtml-if expr="URL[-(_.len('_frame')):]=='_frame'">
  <dtml-call "SESSION.set('select_blueline_temp',select_blueline(_.None,_))">
   <dtml-if expr="error_type == 'SessionNotFoundError'">
    <dtml-return happysession_exception>
   <dtml-else>
    <dtml-return index_frame>
   </dtml-if>
</dtml-if>
</dtml-comment>

Dunno enough about ZPT to understand how it would solve this problem, and 
from what I see of ZPT it appears to mainly be a way to separate the work 
of designers from programmers and I wear both hats, but sure, I'll check it 
out and see you on that list too ;)
