Hi,
I encounter a error when I am using elixir and errorhandling.
@errorhandling.dispatch_error.when("tg_exceptions is not None")
def unhandled_exception(self, tg_source, tg_errors, tg_exception,
*args, **kw):
cherrypy.response.status = 500
return dict(tg_template="testbug.templates.error",
title=_(u"500 Internal Server Error"),
tg_exception=unicode(tg_exception.message))
This is the error handling I am using. It works fine if I did not
login any user. But it throw an UnboundExecutionError if I login with
any user and encounter some exception throw by some function.
For example:
@expose(template="testbug.templates.welcome")
# @identity.require(identity.in_group("admin"))
def index(self):
import time
assert 0, 'failed'
# log.debug("Happy TurboGears Controller Responding For Duty")
flash("Your application is now running")
return dict(now=time.ctime())
Here, if I browse this page, it works fine. The error handler catch
exception and display them correctly. But once I browse this page with
any user I have created, I go error messages:
500 Internal error
The server encountered an unexpected condition which prevented it from
fulfilling the request.
Page handler: <bound method Root.index of <testbug.controllers.Root
object at 0x018ECDD0>>

UnboundExecutionError: Instance [EMAIL PROTECTED] is not bound to a
Session; attribute refresh operation cannot proceed
Error in code generated from template file 'C:\\testbug\\testbug\
\templates\\error.kid'
Why the user instance is not bound to session? The master.kid display
information about user, e.g. user_name of user. Once the template
access the user instance, it throw that exception. I have no idea why
the user instance would be not bound to session after some exception
is throw and catch by the error handler.
I think it might be a bug, could someone help me sole this problem?
Thanks.
Victor Lin.
