Hello dear Siemens experts,

I'm trying to add a feature in my TIA Project where the user can select which “screen ” will be displayed when the HMI starts.

The saving/loading of the user choice works well.

My HMI is based on one screen only where several screen windows are displayed. To ensure the navigation, I created a js function (called "LoadScreen"). This function works well also. 

My issue is related to the Loaded event from my start screen. In this event, I call a function I created called Startup where I execute several tasks (including retrieving the user choice for startup screen). After calling this function, I call my function LoadScreen but it does not work at all. Since I call a “display” function in the Loaded event from screen, is there a delay, so to speak, between the execution of the Loaded event and when all my screen windows are actually displayed on the HMI?

I work with TIA Portal V19 Update on a MTP700 Unified.

OK, I found a solution to make it work. I can help on this topic if anyone interested.
