The ZPublisher uses ":<type>" suffixes in argument names (and
thereby form field names) to convert the (necessarily) string
content to the appropiate type.
And, of cause, it raises an exception, if this is impossible.

If you want do the conversion by yourself, use a different
suffix, e.g. "__<type>". Maybe "-<type>" or something
in the same spirit will work, too.
