allow null on a multi value parameter

Hi,
I don't seem to be able to set "allow null" on a multi value parameter.
I have this parameter with default values from a stored procedure, I want
the report to be able to generate without having something selected from the
multi value parameter. How is this possible?
Bjorn.multi value parameter does not allow NULL.
Just add an empty string to your select statement in SP.
