I'm still not convinced it does; there is no way (that I'm aware of) that a
request parameter would ever be available as a request attribute, so I think
something else is happening there in the code. Most likely something is
putting a model into request scope.

Correct; using map-style (i.e, stopping expression evaluation) works as
expected.
