Description

Problem

Touchstart event is being listening for two views. The customer is listening the touchstart event of the parent view, but when he press the child view he got the touch event of the parent view, and child view.

Reproducible steps:

1. Run the code below 2. Click on the child view ( red square ) After pressing the child view ( red square ) you get the following outputs: [INFO] parent received TOUCHSTART event. Source: child [INFO] parent received TOUCHSTART event. Source: parent

Expected behavior:

The client wants to get the following output when he press the red button. [INFO] parent received TOUCHSTART event. Source: child

Tested with the next specs:

iPhone 3G Version: 4.3.5 iPAD 2 Version: 5 Simulator Titanium Studio, build: 1.0.7.201112080131 Titanium SDK: 1.8.0.1.RC1, 1.8.0.1.v20111205164258 & 1.7.5

More info:

With 1.7.5 Titanium SDK you get the correct expected behavior.

Sample code:

var win = Titanium.UI.createWindow({  
    backgroundColor:'#C08040',
    id: 'win'
});

function parentEventHandler(e) {
	Ti.API.info('parent received ' + e.type.toUpperCase() + ' event. Source: ' + e.source.id);	
}

var sampleParentView = Ti.UI.createView({
	bottom: 0, width: 100, height: 100, backgroundColor: 'yellow',
	id: 'parent'
});

var sampleChildView = Ti.UI.createView({
	width: 50, height: 50, backgroundColor: 'red',
	id: 'child'
});

//sampleParentView.addEventListener('click', parentEventHandler);
sampleParentView.addEventListener('touchstart', parentEventHandler);

sampleParentView.add(sampleChildView);
win.add(sampleParentView);

win.open();
