DataFlex 18.1.45.5 - Beta 2
When a column’s data type is set to MASK_TIME, and columns are also sorted, an error 52 is triggered when the column heading is clicked to re-order.
The solution, I think, lies in cCJGridSortHandler.pkg which does not take into consideration the MASK_TIME data type. Attached is the suggested change (see //[tbs]) and a unit test.
