[Zope] Unhappy HappySession (was Keeping a Variable's Value: This SHOULD Be Easy)

Wed, 31 Oct 2001 13:11:41 +0100

Hi Ben,

How about this?

<dtml-call "SESSION.set('foo', something(_.None,_))">

I still don't understand it fully even though it was explained to me a
few times, but I think its something to do with expressions always
having to satisfy that the method must return something (self).

I tried this (since REQUEST didn't fill the request) and used this line:
<dtml-call "SESSION.set('foo', something)">
where *something* was a dtml method that executed the evaluation of a 
python expression. Now, whereas REQUEST *was* able to execute said 
expression and HappySession *was* happy substituting a simple string, 
HappySession was not happy evaluating the python expression :(

Any more ideas?
TIA,
BenO
