keyboardActivated ... but by whom ???

[Guglielmo Braguglia]

Hi,
anyone knows how to find out, on a card with many native text fields 
(created with mobileCreateControl), which control triggered the keyboard ?

On the "keyboardActivated" message I have tried to test the 
"mobileControlTarget()" but ... return an empty value ... :-(

Any suggestion ?

Thanks in advance,

Guglielmo
