Ask for confirmation in cancel and back envents with Genexus Ev3 for Smart Devices

Question

I need to ask the user for confirmation when he taps the back or the cancel buttons, but only when the transaction is in edit mode. ¿How can I ask the mode for the current transaction?

Event Back
    Composite       
        &Answer= interop.Confirm("If you do this, you could lost all unsaved data. ¿Do you want to continue?")
        if &Answer
            return
        EndIf
    EndComposite
Endevent

I'm working with Genexus Ev3 U2 for Android device.

Thanks

u can try move a parameter moving Y when editing mode.

When u call the sdpanel input a variable &flag char(1) : "Y" when edit and "N" when note editing.

Event back Composite If &flag : "Y" &hasConfirmed = interop.confirm ........... . . . Endcomposite Endevent
