Nullable variable with DataSource

[maxim]

Hi, I have a report that uses a nullable variable with a range of values retrieved from a data source. The variable is a nullable giud which is a primary key on the data source. Preview succeeds if the value is made non-nullable or when not tied to a data source. I added an "empty value" to the data source with null as a key but that didn't help. Is there anything I'm doing wrong?
