Update context variable of another screen

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

Your gallery ThisItem is not refreshed when you patch, so your OnSelect is still using the value from before.

Need to add in a refresh if you want the item to update.

Refresh(datasourcename);;

Hi @Anonymous

Just to avoid any confusion, let's modify the global variable that you set in mesure_preventive_edit_1 to "var_my_item".

Set( var_my_item; Patch( example; my_item; { example; "example" } ) );;

In the button that returns you from detail to mesure_preventive_edit_1, if you set the OnSelect to the following, the data in detail should refresh.

Navigate(detail; ScreenTransition.None;{my_item: var_my_item});;

I tried this which didn't work since my_item isn't defined in mesure_preventive_edit_1.

Set( var_my_item; Patch( example; my_item; { example; "example" } ) );;

I also tried this, but the detail view still contain the old data, so it doesn't seems to work:

Set( my_item; Patch( example; var_my_item; { example; "example" } ) );;
