After applying CU4 on my SQL Server 2012 SP1 installation I can no longer use multi valued parameters in my reports. Scenario: If I have two parameters and the first parameter allows multiple values, the second parameter never gets filtered by the selection made in the first parameter. In fact it never gets activated it remains inactive, and when profiling SQL Server I can see that no query is sent to SQL Server for the seconbd parameter. The problem only occurs after deploying to the report manager (installed in native mode). While developing the report the parameters work fine. I have tried creating the report in both Visual Studio and Report Builder, but after deploying to report manager the report still doesn't work. This became a problem immediately after installing CU4 for SQL Server 2012.
Does anyone else have this problem or suggestions on how to solve this problem??
