Hello There,
V3.3.0, GGC
when I do the customized grouping, it works when the whole column has data. but it got untrackable error when some cell is empty (null) data.
In the attached sample, click button 'col1 classificaiton' to grouping a numeric column 1
and click 'col2 classification' to grouping a datetime column2. Both work well. Now you try to delete some cell value in column1 and in column2 to make the value empty (null), the click the buttons. It doesn't work without display any error message.
The problem must be caused by NULL value. But
I do not know how or where to put break point and try{}catch{} code to track the NULL value and the errors?
Any idea? Thanks.
