I'm trying to catch when someone tries to create an object with the same Id
as another object. I thought this was handled by checkValidId. It doesn't
appear that this error is handled by standard_error_message. Whenever this
error happens, the rror message is not skinned like the site I'm working on
(ie. It's just some very basic html output).

Some "BadRequest" exceptions are not handled by "standard_error_message"
(a bug, please file a bug report). But, this is not the case for the one
Affected are errors detected in "REQUEST.processInputs()".
They are not handled by "standard_error_message" because they are detected
too early -- before traversal has even begun.
As a result, there is not yet any "standard_error_message" in the request
These errors are usually type errors during conversion of request parameters
called for by ":<type>" suffixes, e.g.
"start:int=a" would cause such an error.
The easy workaround is not to use such ZPublisher type conversions but
perform the conversions yourself in your application code.
