I would guess you have the same problem as Diego Rodrigo... could you check
your standard_html_header? Does it make any reference to SESSION?
One thing about HappySession is that I made it so no initialization is
required. So please do not call SESSION object in standard_html_header to
initialize it. (In the next release I'll make it safe even if someone calls
it in standard_html_header.)
I will try to guess what you want to do: you want to initialize FLinkID at
the beginning of the session? If so, since HappySession's dictionary does
not require initialization, you can do something like:
<dtml-if "SESSION['FLinkID'] == _.None">
<dtml-call "SESSION.set('FLinkID', 0)">
... normal operation here ...
(If an item does not exist, SESSION['FLinkID'] returns ._None)
