How can I update the context variable of an another screen?
Here is a example of my workflow.
1. I am in my gallery and I click on the item which will call this Navigate(detail; ScreenTransition.None;{my_item: ThisItem});;

2 I can see the detail of my item by doing my_item.X.

3. I click on the pen which call Navigate(mesure_preventive_edit_1; ScreenTransition.None;{my_item: my_item})
4. Now, I modified some value and I call this (I have also tried with an UpdateContext):
Set(
my_item;
Patch(
example;
my_item;
{
example; "example"
}
)
);;
But, when I go back to my detail view, I can still see the old value. This means that my_item hasn't been updated, but if I go in my SQL database, I can see that the record have been update.
In brief, browse screen → detail screen → edit screen
