[Zope] REQUEST.set doesn't set in 2.2.4

[Brad Clements]

This code:

<dtml-call "REQUEST.set('verrormessage',orderobject.chargeCard(REQUEST,Holmes.CyberCash,Rec))">
<!-- charge result is &dtml-verrormessage;-->

Prints out _.None as the result.

However a print statement in my ordeobject.chargeCard method shows 
that the return value isn't None.

This seems broken. The return code is coming from within an exception 
handler, I wonder if that is related to the problem.

I've also noticed that in a <dtml-try><dtml-except> calling 
REQUEST.set within the except doesn't set it.

Anyone got ideas?
