I keep on trying a way to get this working.
In a previous discussion (see the end of Christian's answer
here<http://markmail.org/thread/w6s3jtmwwfw6vfnx#query:+page:1+mid:jbwboaocfw4lkjqj+state:results>),
a workaround for the null id could be the use of a HeartBeat to defer the
evaluation of the client id value.
had someone already given it a go?
