I spotted some strange scroll behaviour whilst on a client site. Rows seemed to be duplicated in a table, even though the values in the dimension were distinct. The values attached to the duplicated rows were also duplicated, but the total looked fine. On exporting to Excel, no duplicates existed and all looked well.
Subsequently I have done some testing on Qlik Sense Server, Qlik Sense Desktop and Qlik Cloud (3.0 SR1, 3.0 SR1 and 3.1 IR respectively) and found exactly the same problem.
To replicate this issue you can run this very simple load script to get some data:
RowNo() as Row
and then, once the data is loaded create a sheet and then a Table object. Into this drop the only dimension.
Drag the table so that only the first five or six numbers are visible, and then scroll.
Initially the scroll bar seems the right size, but on scrolling down it halves in size and duplicate rows appear. You can see when the table is sorted the point at which the numbers duplicate here:
Behaviour is not entirely consistent, and can change on a reload or resize of the table. The point at which the values repeat shifts (here you can see it is at 9, I've seen it at 10 and 7 also).
Does anyone know what is going on here, and whether there is a way to fix it? mtojgd I feel very uncomfortable handing over apps where this is happening.
