How to return a "OUT" parameter in Genexus Ev3 U1 Smartdevices?

Develop with Genexus Smart Devices Ev3 U1 for Android.

I intend to develop a screen Father that by clicking a button opens the screen Son, where the user selects an item in a grid and returns to the Parent by displaying the clicked item.

But does not return the "out" parameter of the Child.

See how I’m trying:

in the Panel "Father" there is a button with the event below:

Event 'Adicionar Lugar'
Composite
pnPromptCota.Call(&addLugVCOTA_COTACODIGO)
TextblockLugarDs.Caption = &addLugVCOTA_COTACODIGO.ToString()
Interop.Msg('&addLugVCOTA_COTACODIGO= '+&addLugVCOTA_COTACODIGO.ToString().Trim())
EndComposite
Endevent

In the Panel "Son" (Selection Prompt) has a grid with Tap event:

parm(
    out: &VCOTA_COTACODIGO
    );


Event VCOTA_COTACODIGO.Tap
&VCOTA_COTACODIGO = VCOTA_COTACODIGO
SDActions.Return()
Endevent

But when returns brings zero code (in "Interop.Msg....").

For me there is no logic, it seems all right, just as I would in Web programming with Genexus.

What can I change to make OUT return?

I await return. Thank you!

Note: I’ve tried only "Return" instead of "Sdactions.Return()" and it doesn’t work either.

In some app I did something similar to what you mention. It was based on this example. From what I saw in your case the most important difference is that you use the event "tap" (Event VCOTA_CODIGO.Tap) and in the example (and in my case) was configured as "default action" of the "grid". Suddenly, you can try to implement it as in the example.
