Okie, now I see why you get the Transaction error problem. After an
exception is raised, Zope aborts the http request transaction, and any
attempt to further use Zope objects that are transaction-aware will cause an
error. In the next release of HappySession I will try to detect whether the
transaction has ended, and return some meaningless result like None. But the
real thing is, after the exception happens, SESSION object should not be
If you really need to call SESSION in your standard_html_header, then please
do two things:
(1) Please use a standard_error_message, and it should start with something
<dtml-if "not error_message and error_type == 'SessionNotFoundError'">
(2) In your session_not_found_html, please do NOT use <dtml-var
standard_html_header>. Instead, write another DTML and call it
session_ended_html_header, and use it instead. Inside your
session_ended_html_header, please do NOT call the SESSION object.

(Hmmm... multiple SESSION objects... in typical situations usually one
single SESSION object should be enough. Notice that two SESSION objects mean
two separate storage. Although HappySession is designed to handle multiple
SESSION objects sharing the same key cookie, the expiration time might be a
tricky issue... I do not recommend multiple SESSION objects.)
The thing I don't understand is why you need to make explicit call to the
SESSION objects. Ohh...! I see, you probably think that SESSION objects need
to be initialized? OK, unlike FSSession or SQLSession, HappySession's
SESSION objects do NOT need to be initialized! You don't need to make an
explicit call to SESSION in your standard_html_header. HappySession is smart
enough to initialize itself whenever you touch it the first time using any
of its methods. No explicit initialization call needed.
(I'll add an observation on this in the help file in the future.)
In short, I think that by simply removing your callSession method and its
reference in standard_html_header, you will be fine and happy! :)
