bug in FillRealTabOrders - mazluta - 07-16-2020
hi think there is bug in - the list is not maintained correctly and some of the obj in the list don't exists
so - the render crash
------------------------------------ this is my bypass
procedure TIWForm.FillRealTabOrders;
procedure FillList(AContainer: TIWContainer; AList: TIWListBase);
var
i: Integer;
LCurrent: TObject;
LTabOrderInterface: IIWTabOrder;
begin
for i := 0 to AContainer.TabOrderList.Count - 1 do
begin
Try //Yossi
LCurrent := TObject(AContainer.TabOrderList[i]);
if Assigned(LCurrent) then //yossi
begin
if LCurrent is TIWContainer then
begin
FillList(TIWContainer(LCurrent), AList);
end
else
begin
LTabOrderInterface := TabOrderInterface(LCurrent);
if LTabOrderInterface <> nil then begin
if LTabOrderInterface.HasTabOrder then begin
AList.Add(LCurrent);
end;
end;
end;
end;
Except //yossi
on e: exception do
begin
Try
logFileAppend('Error on TabOrder FillList : I= ' + IntToStr(I) + ' Message= ' + e.Message);
Except;
End;
end;
End;
end;
end;
begin
FRealTabOrderList := TIWListBase.Create;
FillList(Self, FRealTabOrderList);
end;

What version is that?
The code is correct. The problem usually comes from controls without parent being created and destroyed on the fly which bypass the TComponent notification mechanism completely. Are you doing it?
RE: bug in FillRealTabOrders - mazluta - 07-17-2020
15.2.4
the is correct. but the list is not maintained correctly, so i gat access violation.
i have some frames and inside frame. when i free one frame and try to create another. i think, it try to render the freed frame.

Please post a ready to run demo that demonstrates your issue for us to see. Posting code snippets not only often leaves out code that is important and interacts, but slows down support requests as we have to try to recreate the issue from code snippets.

please see - attached - project 1
RE: bug in FillRealTabOrders - Alexandre Machado - 07-20-2020
The attached demo project doesn't crash using latest 15.2.6. Have you tested it?
The issue that you claim that is not working is a rendering issue regarding jQGrid which you reported again in another thread.
