TAdvOutlookList grouping issue

Dood Day!

I have a problem with grouping in TAdvOutlookList.
I have created 3 integer columns, 2 text columns, 1 integer column and 1 date column (I mean sort SortType of the column). When property GroupColumnDisplay is set to gdVisible I can sort all columns but 3 integer and last Date not. I got an error message "EConvertError" and the value from first text column and for Date column an empty string. When property GroupColumnDisplayis set to gdHiddenaverything is working just fine.

Could you please to help.

Thanks in advance.
