keyEvent.getKey() == 4 short vrs long pressed

Hi! I have the following problem, you might know the reason/solution.

I have the following code line:  if (keyEvent.getKey() == 4) {onSelect_lauch();}

I found that, in the simulator, for several devices, when I press the "Start-Stop buttom" (Key 4), if I press it long (not just one click but a "long" click), it launches properly the function but if I press it short, I gives me the typical error "Symbol Not found Error". It is an App (not a widget).

Error: Symbol Not Found Error

Details: Failed invoking <symbol>

Stack:

Do you know why and how to solve it?

Thanks!

    You may want to only do "return true" for keys you handled and "return false" for the others.

    Seems that the following code works well:

    public function onKeyReleased(evt as KeyEvent) as Boolean {
            var key = (evt.getKey());
            if (key == WatchUi.KEY_ENTER) {
                onSelect_Battle();
            }
            return true;
        }

    I am using the Forerunner 645m, but happens the same in several devices. What do you mean with "to return a value in your onKey function"?

    If I do:

    function onKey(keyEvent) {
            if (keyEvent.getKey() == 13) {slide_left();}
            if (keyEvent.getKey() == WatchUi.KEY_ENTER) {onSelect_Battle();}
        }
    public function onSelect_Battle() as Boolean {
            System.println("Activated")
            return true;
        }
     
    It works well with "long" and "short" press. I do not know why with if (keyEvent.getKey() == WatchUi.KEY_ENTER) {onSelect_Battle();} it does not work with short press.
     
    If istead of KEY_ENTER ( number 4) I use aother button, the 13 for example it works perfect, but I need to use the 4 (key_Enter).
    Might be the sim that is not working properly?
    Thanks!

    You need to return a value in your onKey function.  You also may see things on a real device you don't see in the sim.  On something like a venu2, long press of the upper right botton will take you to the controals screen/

    You really need to say what device you are using in the sim.

    Thank you Jim for your answer. I have already checked the input example. Button 4 is KEY_ENTER. There is no difference if short or long pressed, just the pressed / not pressed status, but does the same. I tried with several Forerunner and other watches devices with buttons.

    The code is:

    function onKey(keyEvent) {
            if (keyEvent.getKey() == 13) {slide_left();}
            if (keyEvent.getKey() == WatchUi.KEY_ENTER) {onSelect_Battle();}
        }
    public function onSelect_Battle() as Boolean {
            WatchUi.pushView(new $.Steps_Battle_AttackView(), new $.EntryMenuDelegate(), WatchUi.SLIDE_BLINK);
            return true;
        }

    When pushed fast the KEY_ENTER, gives the error, if pushed "slow" it works. Similar response if: if (keyEvent.getKey() == 4) {onSelect_Battle();}

    If I change to function to the following one, it works for short and long pressed.

    public function onSelect_Battle() as Boolean {
            System.println("Activated")
            return true;
        }
    I am totally blocked.
    Thanks!
