UI in a split mode

[kuzmao]

Hi,

When redundant servers are in split mode and UI is open I receive following message into log after successful login using login panel.

WCCOAui (9), 2022.01.12 07:52:08.919, CTRL, SEVERE, 17/ctrl, Cannot find dollar parameter $System. Location:
Module: Vision_1
Panel: C:\Siemens\Automation\WinCC_OA\3.18\panels\vision\login.pnl [Login]
Object: 0 named: "btn_Action" of type: PUSH_BUTTON
Script: Clicked
Library: C:\Siemens\Automation\WinCC_OA\3.18\scripts\libs\dist.ctl
Line: 1989

The project is redundant, distributed. Problem appears on Windows/Linux, using 3.18P6.

We will test if we can reproduce this error.
I checked the code but without a test I could not see possible causes.
