错误＃2007：参数孩子必须为非空 [英] Error #2007: Parameter child must be non-null

问题描述

有没有什么错误，但今天！这将是很好的sooo得到一点帮助，这一个。

我调用外部子SWF为AIR应用程序;超级简单 - 称他们有一个按钮，并配有家的按钮，清除他们，仅此而已。但我得到这些错误，我不能公布，甚至一个测试，而不使整个系统崩溃。请帮忙！我一直坚持这一点，从字面上看，几个星期！

这是错误：

 类型错误：错误＃2007：参数孩子必须为非空。
在flash.display使用::级DisplayObjectContainer / removeChild之（）
在pocketDinos_fla :: MainTimeline / fl_ClickToGoToAndStopAtFrame_20_1（）
[pocketDinos_fla.MainTimeline :: frame162：18]
测试影片结束。
 

这就是我认为是造成主时间轴上的问题（这是所有主时间轴上的code）：

不过，我还是我有孩子文件没有加载设备本身的问题 - 奇怪 - 他们加载罚款测试的出口，而不是当我发布到设备（在这种情况下，IOS）。有没有人有什么想法？

Having nothing but errors today! It would be sooo nice to get a bit of help with this one.

I am calling external child swfs for an AIR app; SUPER SIMPLE - calling them with a button, and removing them with a "home" button, that's it. But I get these errors and I cannot publish, even a test, without crashing the entire system. Please help! I have been stuck on this, literally, for weeks!

this is the error:

TypeError: Error #2007: Parameter child must be non-null.
at flash.display::DisplayObjectContainer/removeChild()
at pocketDinos_fla::MainTimeline/fl_ClickToGoToAndStopAtFrame_20_1()  
[pocketDinos_fla.MainTimeline::frame162:18]
Test Movie terminated.

And this is what I assume is causing the problem on the main timeline (this is ALL the code on the main timeline):

 stop();

//home button

button_home.addEventListener(MouseEvent.CLICK, fl_ClickToLoadUnloadSWF_01_1,false,0,true);

function fl_ClickToLoadUnloadSWF_01_1(event:MouseEvent):void
{
removeChild(fl_ProLoader_01);
fl_ProLoader_01.unloadAndStop();
fl_ProLoader_01 = null;
}

button_home.addEventListener(MouseEvent.CLICK,     
fl_ClickToGoToAndStopAtFrame_01_1,false,0,true);

function fl_ClickToGoToAndStopAtFrame_01_1(event:MouseEvent):void
{
removeChild(fl_ProLoader_01);

}
button_home.addEventListener(MouseEvent.CLICK, fl_ClickToStopAllSounds_01_1,false,0,true);

function fl_ClickToStopAllSounds_01_1(event:MouseEvent):void
{
SoundMixer.stopAll();
}

button_home.addEventListener(MouseEvent.CLICK,     
fl_ClickToGoToAndStopAtFrame_01_2,false,0,true);

function fl_ClickToGoToAndStopAtFrame_01_2(event:MouseEvent):void
{
gotoAndStop("home");
}

//back to time period button

back_to_triassic.addEventListener(MouseEvent.CLICK,    
fl_ClickToLoadUnloadSWF_01_2,false,0,true);

function fl_ClickToLoadUnloadSWF_01_2(event:MouseEvent):void
{
removeChild(fl_ProLoader_01);
fl_ProLoader_01.unloadAndStop();

}

{

}
back_to_triassic.addEventListener(MouseEvent.CLICK,    
fl_ClickToStopAllSounds_01_2,false,0,true);

function fl_ClickToStopAllSounds_01_2(event:MouseEvent):void
{

}

back_to_triassic.addEventListener(MouseEvent.CLICK,

function fl_ClickToGoToAndStopAtFrame_01_4(event:MouseEvent):void
{
gotoAndStop("TRI_home");
}


//start button

import fl.display.ProLoader;
import flash.events.Event;

var fl_ProLoader_01:ProLoader;

function fl_ClickToLoadUnloadSWF_01_3(event:MouseEvent):void
{
if(fl_ToLoad_01)
{
    fl_ProLoader_01 = new ProLoader();
    fl_ProLoader_01.load(new URLRequest("dinofilms/triassic_coelophysis.swf"));

fl_ProLoader_01.contentLoaderInfo.addEventListener(Event.COMPLETE,onComplete_01)
    addChild(fl_ProLoader_01);
    fl_ProLoader_01.x = 0;
    fl_ProLoader_01.y = 144;
}
else
{
    if(fl_ProLoader_01!=null) {
        removeChild(fl_ProLoader_01);
        fl_ProLoader_01.unloadAndStop();
        fl_ProLoader_01 = null;
    }
}
fl_ToLoad_01 = !fl_ToLoad_01;

}

function onComplete_01(e:Event):void {
e.currentTarget.content.addEventListener(Event.ENTER_FRAME,OEF_01);
}

function OEF_01(e:Event):void {
if(e.currentTarget.currentFrame==e.currentTarget.totalFrames) {
    e.currentTarget.stop();
    e.currentTarget.removeEventListener(Event.ENTER_FRAME,OEF_01);

    removeChild(fl_ProLoader_01);
    fl_ProLoader_01.unloadAndStop();
    fl_ProLoader_01 = null;
}
}

解决方案

I think it got solved!

stop();

//home button

button_home.addEventListener(MouseEvent.CLICK,     
fl_ClickToGoToAndStopAtFrame_01_1,false,0,true);
function fl_ClickToGoToAndStopAtFrame_01_1(event:MouseEvent):void
{
if(fl_ProLoader_01 && fl_ProLoader_01.stage){ 
 fl_ProLoader_01.parent.removeChild(fl_ProLoader_01);}
 gotoAndStop("home");
 }


button_home.addEventListener(MouseEvent.CLICK, fl_ClickToStopAllSounds_01_1,false,0,true);
function fl_ClickToStopAllSounds_01_1(event:MouseEvent):void
{
SoundMixer.stopAll();
}



//back to time period button


back_to_triassic.addEventListener(MouseEvent.CLICK,     
fl_ClickToGoToAndStopAtFrame_01_3,false,0,true);
function fl_ClickToGoToAndStopAtFrame_01_3(event:MouseEvent):void
{
if(fl_ProLoader_01 && fl_ProLoader_01.stage){ 
 fl_ProLoader_01.parent.removeChild(fl_ProLoader_01);}
 gotoAndStop("TRI_home");
 }

back_to_triassic.addEventListener(MouseEvent.CLICK,     
fl_ClickToStopAllSounds_01_2,false,0,true);
function fl_ClickToStopAllSounds_01_2(event:MouseEvent):void
{
SoundMixer.stopAll();
}

However, I still am having the problem that the child files are not loading on the device itself - strange - they load fine on "test" export, but not when I publish to device (in this case ios). Does anyone have any ideas?
