null Date in CountDistinct group header field causes runtime exception

Posted: Sun Sep 12, 2010 9:32 pm
by dcleyne
Folks,

Have another issue with aggregate fields in a group header situation. This time it involves CountDistinct and Date fields. When I have a dataset with null date values the report throws a runtime error. Is there a way to work around this?

Cheers,
Dan
