TOUCH_BEGIN calls function twice

it has a life of it's own!

but removeChild is what bothers me now...

Don't worry. Simply don't use TOUCH_END with exact object. Like a movieclips.

Use TOUCH_BEGIN for movieclip/sprite, but always use stage for TOUCH_END. This will help you controlling TOUCH_END if you removeChild before than TOUCH_END will occur.

import flash.events.TouchEvent;

import flash.ui.Multitouch;

import flash.ui.MultitouchInputMode;

import flash.geom.Point;

// Enable touch input mode because in devices always used Gestures as defaults

Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;

// Create object that will contain all user touches ids with properties

var touchPoints : Object = {};

// add touch listener

Any_DisplayObject.addEventListener(TouchEvent.TOUCH_BEGIN, TOUCH_BEGIN_FUNC);

stage.addEventListener(TouchEvent.TOUCH_END, TOUCH_END_FUNC);

function TOUCH_BEGIN_FUNC (e:TouchEvent):void{

   // save current touch point id to object

    // exactly we save here current touch position as point

     // note if you will use e.localX and Y - this will return local "mouseX" and "mouseY" in your MovieClip. Not global. For example your stage.stageWidth & stage.stageHeight = 960x640 and you will have there square MC in x=300 & y=100

     // localX and Y will return not 300 + offset and Y the same. It will return from 0 to maximum X and Y depending on your square.

     // If you want know exact touch coordinates on screen - you can simple use e.stageX and e.stageY

    touchPoints[ e.touchPointID ] = new Point(e.localX, e.localY);

    // you can use many objects so this will help determinate exact one

    // that was touched

    if ( touchPoints[ e.touchPointID ] ) {

        trace ( "You touch some point in X:", touchPoints[ e.touchPointID ].x, "Y:", touchPoints[ e.touchPointID ].y );

    }

}

function TOUCH_END_FUNC (e:TouchEvent):void{

    // during TOUCH_END event we can check if this TOUCH_END was registered

    // in touchPoints object

    if ( touchPoints[ e.touchPointID ] ) {

        // if touch was registered - do your code things

        trace ( "You just released touch point saved in", touchPoints[ e.touchPointID ].x, "Y:", touchPoints[ e.touchPointID ].y );

        // you need to delete it because after touch for exact point is ends

        // we are good programmers, we don't like unused but not free memory

        // so simply delete information about current touchpoint in object

        delete touchPoints[ e.touchPointID ];

    }

}

in fact - this sometimes occur on iPhone 4 and iPhone 3GS with any Air SDK. Simply I don't have another devices for test. But ! This happen when you have more than 2 touch point id at once. But this simply can be solved - use saving of current pressed touchpoint and chen when you doing decrement so if your exact touch_begin ID point was touch_end - than you will do i--. In another case do nothing =)

This will help you at 100% I done this many times

and which SDK?

looking at your code, nothing is wrong, bug perhaps? what is your device? i have never seen that happen before

function touchEnd(evt:TouchEvent)

{

    i--;

trace(i);

}

may be this help?

but anywhere - you should 'save' your touchpoint id and if it wass released - just for decrease for it.
