TIWTreeView fail on Clear - macropolo - 05-24-2024
Hi,
I'm experincing problems with TIWTreeView that persist even in v15.6.1
The problem typically is that the ClearAll method drives to frequent exceptions of this type:
[2024-05-24, 13:14:41.563] TreeView Before Call [TIWTreeView].ClearAll - Items Count: 450
[2024-05-24, 13:14:41.580] TreeView ERROR After Call [TIWTreeView].ClearAll - Invalid pointer operation
[2024-05-24, 13:14:41.789] Access violation at address 0000000000CE4106 in module 'HSCCSManagerWeb.exe'. Read of address 0000000000000000
It event is generated if I perfom this sort of individual cleaning:
tvSTtransactions.Items.BeginUpdate;
for var i := tvSTtransactions.Items.Count - 1 downto 0 do
begin
tvSTtransactions.Items.Delete(i);
end;
tvSTtransactions.Items.EndUpdate;
No extra information is retrieved from those exceptions. Has anybody solved it in a different form?
@Alexandre Machado, could you please check what can be buggy on the sources of the component?
Thanks in advance. Regards, Pablo.

Seems that you are using x64 bit, is that correct?
I'll try o recreate it here and let you know.
