[Zope] unexpected failure....

[Jens Vagelpohl]

I was just playing with a database connection and had made up a form to
collect some data, which calls a page giving feedback and at the same time
the ZSQL method to do the actual processing. This stuff was successful the
first few times, but all of a sudden Zope restarts. I get a "Page cannot be
displayed" error. Checking the database I see that the record has not been
added.

The ZServer log (var/Z2.log) doesn't show anything about it.

This is what appears on the command line from where i started Zope:

uncaptured python exception, closing channel

])


What could the reason be? does "exceptions.KeyError:String" imply that I am
misusing a string in the input data? Even when i just leave out all fields
that don't require input data I still get the error. The only fields I am
passing, apart from empty strings, are two integer values.
