_GUICtrlListView_GetItemChecked reporting False after _GUICtrlListView_GetItemText twice

[Page2PagePro]

Using example: https://www.autoitscript.com/autoit3/docs/libfunctions/_GUICtrlListView_SetItemChecked.htm

This works as expected.

However, if two or more _GUICtrlListView_GetItemText with two different SubItems for same Index/Row precede _GUICtrlListView_SetItemChecked, the latter function reports False incorrectly.

MsgBox($MB_SYSTEMMODAL, "Information", "Item 0 0 Text: " & _GUICtrlListView_GetItemText($idListview, 0, 0))
MsgBox($MB_SYSTEMMODAL, "Information", "Item 0 1 Text: " & _GUICtrlListView_GetItemText($idListview, 0, 1))

 

Here is complete code (minimally altered from example):

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include <MsgBoxConstants.au3>

Tested in both 64-bit and 32-bit (#AutoIt3Wrapper_UseX64=N) - same.

When referencing the SubItems 1 then 0 (vs. code above which is sequential 0 then 1) the bug does not surface.

i.e.: Working As Expected (changed from MsgBox to ConsoleWrite - note the second time the checkbox is inspected, False is returned in lieu of True.

I do understand this is BETA.

Thank you all for your *kind* feedback :)

I can confirm this problem on 3.3.15.3 (on 3.3.14.5 it's OK) , but disabling X64 solves this problem:

 

Add this at top of script:

#pragma compile(x64, false)

 

So problem is probably with not X64 compatible code somewhere inside (new?) UDFs ...

 

EDIT2: rechecked now

compile as X32 helps only on Win10 (on Win7 it doesn't help)

compile as X32 doesn't help neither on Win10  nor on Win7
