Date Picker RS2005SP2 useless

I read a lot of posts in this forum, but none of them provide a solution.

Probably it is related to SP2 as many report, I have SP2 as well...

A funny situation:
I have a report parameter @.date, datatype datetime, so I can use the datepicker control.

But, even when not using this @.date parameter in my dataset, I still get the error:

The value provided for the report parameter 'date' is not valid for its type. (rsReportParameterTypeMismatch)

Of course it has to do with regional settings and languages etc... But at my international client's site, workstations are in any regional setting and servers are in en-US, nothing I can do about that.

Come'on Microsoft, don't tell us this datePicker is only for the US market?

Thank You MS!

Apparently it is now solved in the Cumulative update package 2 for SQL Server 2005 Service Pack 2
