I am creating a report and trying to filter it down to certain locations. Our IDs are all uniqueidentifiers. When i try to do $X{IN,Table.LocationID, LocationID} Where the LocationID is a defined parameter as a java.util.Collection class type I get the conversion failed. How can I get results for my report where a Guid is in the passed in collection? I have tried Casting the Table.LocationID as varchar and that didn't work.
