      This problem continues in v7.23.

        Please check the version 7.24 – I have added some checks there, but I can't understand why you have this error.

        Maybe you can show me a demo?

        Problematic line can't be commented because Data property may be used in many projects…

          I found the problem – and it was my fault. Apparently v6 must have been tolerant of this mistake but v7 was not. Thank you for checking anyway – and my apologies.

          Example of logic error:

          Code:
          sListbox_EntityControl.items.clear;

          for iX := 1 To iEntSize do
          begin
          sListbox_EntityControl.items[iX-1] := szText;
          end;

          Repaired logic:

          Code:
          sListbox_EntityControl.items.clear;

          for iX := 1 To iEntSize do
          begin
          sListbox_EntityControl.items.add(szText);
          end;
