Hi,
i have a label wich gives a haptic-feedback on "click". After that i have called this sub (label_Click) also by the _EnterPressed-event from a textbox. My problem is, that
B4X:
XUIViewsUtils.PerformHapticFeedback(Sender)
inside the label_Click raises an error.
B4X:
HapticFeedback failed
(Exception) java.lang.Exception:  java.lang.RuntimeException: Object should first be initialized (B4XView).
Error occurred on line: 24 (XUIViewsUtils)
java.lang.RuntimeException: Object should first be initialized (B4XView).

I´m sure it is because a missing sender - but how can i transfer a "correct" sender...

Thanks!

Edit: the name of the label is working - don´t know why it´s not working in the first test - maybe i forgot to restart the app...
