TouchEvent Down and Up sometimes fire and sometimes not

[ Edited ]

Hello all,


bb::cascades::TouchEvent mouse down and mouse up some times fired and some times not


here isa a sample of my code

I put imageButton in QML


     ImageView {
                         id: imgHand
                         imageSource: "asset:///images/swipe3.png"
                         scalingMethod: ScalingMethod.Fill
            horizontalAlignment: HorizontalAlignment.Center
            verticalAlignment: VerticalAlignment.Center
            onTouch: {


and CPP:


void Aio::handleTouch(bb::cascades::TouchEvent* event) {
	if (event->touchType() == TouchType::Move) {
		fprintf(stderr, "Debug:move %f\n", event->windowX());
	} else if (event->touchType() == TouchType::Up) {
		fprintf(stderr, "Debug:up %f\n", event->windowX());
	}else if (event->touchType() == TouchType::Down) {
		fprintf(stderr, "Debug:down %f\n", event->windowX());



I found that "Up" and "Down" sometimes called and sometimes not.  


Please test this on your devixe and let me know if you have the same issue or not.
