In VisualStudio/BIDS, I am experiencing odd behavior with a parameter that is a date/time data type with available values that come from a query. When I try to run the report after selecting a date, the parameter is reset to blank and the body of the report remains blank. It's as if the report environment just resets. If I change the data type to Text, the report runs fine. And if I change the available values to a specific value list, the report runs fine. And if I deploy the report and run it from Report Manager, it runs fine. It is only in BIDS with those particular options that it has a problem.
Could there be some corruption in the RDL that is just affecting BIDS? Is any one else experiencing a similar symptom?
