Labelcaption in Tadvedit can not be changed

VCL TMS VCL UI Pack

Since 30 May 2018 update, the LabelCaption of a Tadvedit can be set or be empty but can not be changed or re-set after being empty.

What exact steps to execute? Does this concern design-time ? run-time ? Both?

I cannot see an issue here to set the LabelCaption to a text or empty both at design-time and run-time.

put a tadvedit in a form and set labelcaption twice to see it
I did a quick fix in TCustomAdvEdit.SetLabelCaption with the following change:
  if (FLabel = nil) and (Value <> '') then
  begin
    FLabel := CreateLabel;
    FLabel.Caption := Value;
    UpdateLabel;
  end
  else
  if Assigned(FLabel) {and (Value = '')} then
  begin
    FLabel.Caption := Value;
    UpdateLabel;
  end;

My advedit's version : 3.4.6.1

That clarified it. Thanks for reporting. We've applied a fix for this.
