TypeError: 'NoneType' object is not callable

[Jorge Godoy]

I started getting this famous error, what didn't happened before. I noticed
that this happens when I enter several forms of mine. If I restart the
application and reload the page, it works perfectly... Then, I start
navigating and after four or five pages (other forms), it happens again -- and
then, every form fails...

Can anybody suggest me something to solve this problem?

The page, when the problem happens, is supposed to render a fastdatagrid
only.

Are you sure the error can't be caused by mere programming logic error
-- e.g. you try to call None in your template?

Positively sure. If it was like that, it wouldn't have worked before and it
wouldn't work with just a refresh of the page after the restart.

For what it's worth, I'm getting essentially the same stack trace with
the same frequency and the same behavior (restart, reload everthing's
fine for a while then boom again).

I was getting the same error some times ago in fastdata, are you
running the latests kid and turbokid?

I am. TurboKid 0.9? I've tried easy_install before reporting this error
here. And I'm using Kid from SVN trunk.

I think so. Is there an easy way to tell before I re-do an easy_install
. in the appropriate thirdparty directories?

Keith,

run "tg-admin info" anywhere to see what all you have installed.
Also, Turbokid is in plugins/kid, not thirdparty/kid (kid is there).

I'm also running into this error, with TurboKid 0.9.0 and kid 0.8. Kid
0.9 gives me a bizarre sitetemplate error that I've been unable to
track down. Just upgraded to turbokid 0.9.1, so I'm hoping it'll clear
up.

I'm not sure you guys have already solved this problem, but this was
bitting me too and upgrading TurboKid seems to have solved it for me.
In this case, I upgraded from TurboKid 0.9.0 to TurboKid 0.9.1dev-r787
(which was sitting in my plugins/kid since I pulled TG from SVN a
couple of days ago).

Cheers,

P.

Hi Richard,

I think you should upgrade your TurboKid.

Ciao
Michele

[Richard (koorb)]

Hey Michele,

Just tried, tells me 0.9.0 is already the active version? is there a
specific development version I need?

[Richard (koorb)]

oh hey, just tried easy_install -U to force upgrade 0.9.1 all seems
well!

[Mike Sarahan]

Richard,

how are you trying to get the new version?

the best way to get the latest of turbokid is to go into the
plugins/kid dir of your trunk checkout, and run "easy_install ."

I haven't upgraded since february 20th (if it isn't broken, don't fix
it), and my turbokid version is 0.9.1dev-r787

Also, you might try doing the same thing for kid (but it's in
thirdparty/kid) - I noticed your version is 0.8. Mine is 0.9. I
believe the fix has been in turbokid, but this might be something else
to try.

I don't know if the above instructions work with the alpha release.
Haven't tried it yet. If those folders exist, though, give it a shot.

-Mike
