Passing null parameters via Query-String

I'm trying to call a report, passing my parameters via query-string...
I have one parameter that can receive null values...
Following Books Online, the syntax for null values is :isnull, giving the following sample of URL:
http://exampleWebServerName/reportserver?/foldercontainingreports/orders&division=mailorder®ion=west&sales:isnull
In my report, I shadowed this syntax, it looks like the following:
http://localhost/ReportServer?/ctr_es_reports/entrada_saida&dh_ini=2004-06-01&dh_fim=2004-07-20&func_cd_matricula:isnull
If I pass a common value to func_cd_matricula, like 1 or 2, it works fine, but with this isnull syntax, it gives me the following error:
"The path of the item '/ctr_es_reports/entrada_saida,func_cd_matricula:isnull' is not valid. The full path must be less than 260 characters long, must start with slash; other restrictions apply. Check the documentation for complete set of restrictions."
Does anybody know why this?
Thanks,
Rafa®BOL is incorrect.
Right syntax is
sales:isNull=true
