500 Server error with IFrames?
wul...@gmail.com
Firstly I created a *.kid page which is passed some DB vars to display
in a table. (this file called widget.kid).
Secondly I create another *.kid page (the top level page) which has
several (5+) IFRAMES which embed the above widget page.
The problem I have having is that on a page refresh for the top level
page, one or more of the IFRAMES randomly returns a "500 internal
error". Sometimes all IFRAMES load properly (no errors), sometimes one
(random selection) returns the error, and sometimes more than one
return the error.
When the IFRAME loads properly, all the content is there and is also
formatted correctly. I have no other problems with the pages.
Yes I have restarted the server after any changes to my files. I am
using TG Alpha 0.9x on OSX 10.3 867Mhz G4.
Does anybody have any clue what might be the problem?
Below is the error message itself.

do a search for that on the mailing list archive, it seems to be one of those bugs that something happen but not all the time.

Does anyone know the solution?
I am using turbogears from SVN, it was a fresh install about a week
ago. Since then I have butted my head on the desk many times. At
first I thought it was because of this, then that, then the next thing,
but today, I am still getting these errors. I have searched the group
archives, but I have not found any real cause or solution.
It seems to be completely random. The only way I can fix it for now,
is to restart the server after removing all template.pyc files.

This message was sent from the google site, in response to a thread
originally titled: "TypeError: 'NoneType' object is not
callable". I suppose I should have taken more care to check the
subject before spamming nearly 2000 people. It shan't happen again.
I was however, almost beside myself. I am still receiving these errors
on a completely random schedule. So far, since last night, I haven't
had too much of a problem, but, at one stage, my site was virtually
undevelopable. I would remove .pyc files and re-touch all others (I
have a batch script to do so now), to no avail. I am lost. I have seen
some notes on tentative fixes, but the paths mentioned do not exist in
my installation. I've seen also a few posts about things which don't
affect me at all, like items I do not have installed, etc.
At one stage, I thought that it was the following code, which should not
have a 'raise' before it (though it works, either way):
>>> from turbogears import redirect
>>> ...
>>> raise redirect(URL)
-- That seemed to clear the errors up sharp, for a while, but the
fragile peace was not to last.
Any help would be mightily appreciated.
Thanks (and sorry again for the bad email)!

object is not callable" error?
I *think* the previous ones I've seen of this are usually Kid-
related. I'm not in a position right now to take a look deeper into
this, unfortunately (I still have some prep to do for EuroPython
tomorrow...)
