If you place a breakpoint on the first statement
sRadioGroup1.ItemIndex := 0;
And try to put a watch on ItemIndex, my Delphi IDE (my Delphi is XE4) throws an access violation. It doesn’t do that on the second statement
RadioGroup1.ItemIndex := 0;
Something is terribly wrong 🤢

Thank you for the demo, it will be fixed in the v15.13 ItemIndex value is changed, just Checkbox not refreshed there.
Where execution is stopped when AV is occured? (Can’t repeat AV)

The IDE itself throws an exception when trying to add a watch. App is not running then.

This is the exception, if I press Ctrl-F7 upon reaching a breakpoint on the first statement (AC 15.13)
The problem of not refreshing is solved.

This IDE exception is repeated?
How can I repeat it step-by-step?

[HeDiBo]

The compiler is Delphi XE4. The debug environment is Win32.
Set a breakpoint on this statement:

procedure TBaseForm.sButton1Click(Sender: TObject);
begin
   sRadioGroup1.ItemIndex := 0;   << Set a breakpoint on this statement.
   RadioGroup1.ItemIndex := 0;
end;

Click the button “Select One”
Upon reaching the breakpoint, click on the first ItemIndex property.
Then press Ctrl-F7 (Evaluate/Modify).
I get an Internal Error : F2084 Internal Error: AV06EA8554-R80000000-0

I think, this internal error is linked with big amount of links between units in the package.
Other version of th Delphi hasn’t this issue.
I will check what I can do there.

Not solved in 15.15

Sorry, I was checked links between units and they are optimal now, I think.
Haven’t idea how to solve this internal error. I only saw articles like this in the net.

It seems a compiler error. Don’t bother.
Please close this topic.
