    copied!<pre><code>ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. </code></pre> <p>so i have a function that runs in state1 and has a </p> <pre><code>while(myCanvas.rawChildren.numChildren &gt; 0){ myCanvas.rawChildren.removeChildAt(0); } //this code is definitely the problem.... </code></pre> <p>I can move to state2, but when I move back to state1 i get the error.</p> <p>why? the function that has the while loop only runs when something is searched in state1, so why is it running when coming back from state2?</p> <p>edit... </p> <p>so i did i test for a function that runs at app initialization:</p> <pre><code>private function init():void{ trace(g); if(g == true){ while(myCanvas.rawChildren.numChildren &gt; 0){ myCanvas.rawChildren.removeChildAt(0); } g = false; } trace(g); } </code></pre> <p>It shouldnt run one it comes back to state1, but i still get the error. So basically as long as that while loop runs once while in state1 I can never get back to state1</p> <pre><code>&lt;mx:states&gt; &lt;mx:State name="contactform"&gt; &lt;mx:AddChild position="lastChild"&gt; &lt;mx:Canvas id="msgCanvas" backgroundColor="0xEEEEEE" height="121" y="158" width="800" fontWeight="normal" fontSize="12" backgroundAlpha="0.02" x="0"&gt; &lt;/mx:Canvas&gt; &lt;/mx:AddChild&gt; &lt;mx:AddChild position="lastChild"&gt; &lt;custom:email_cmp x="150" y="287" height="213"/&gt; &lt;/mx:AddChild&gt; &lt;/mx:State&gt; &lt;mx:State name="main"&gt; &lt;mx:AddChild position="lastChild"&gt; &lt;mx:Canvas id="myCanvas" backgroundColor="0xEEEEEE" height="342" y="158" width="800" fontWeight="normal" fontSize="12" backgroundAlpha="0.02" x="0"&gt; &lt;/mx:Canvas&gt; &lt;/mx:AddChild&gt; &lt;/mx:State&gt; &lt;/mx:states&gt; public function mainFunction():void{ origArray = []; var cache:int = 0; if(myCanvas.rawChildren.numChildren &gt; 0){ myCanvas.rawChildren.removeChildAt(0); } //text format for links var hFormat:TextFormat = new TextFormat(); hFormat.font = "Verdana"; hFormat.color = 0x000000; hFormat.size = 15; //text format end var sprite1:Sprite = new Sprite(); var textQ:TextField = new TextField(); textQ.mouseEnabled = false; if(amt_cnt.count == 1){ amt_cnt.end = amt_cnt.endCache; amt_cnt.start = amt_cnt.startCache; //set the text textQ.defaultTextFormat = hFormat; textQ.text = "Still can't find your answer? Need more help?"; textQ.x = 270; textQ.y = 300; textQ.width = textQ.textWidth +20; textQ.selectable = false; sprite1.addChild(textQ); sprite1.buttonMode = true; myCanvas.rawChildren.addChild(sprite1); sprite1.addEventListener(MouseEvent.CLICK, moreHelp); }else{ amt_cnt.end = amt_cnt.endCache; amt_cnt.start = amt_cnt.startCache; textQ.defaultTextFormat = hFormat; textQ.text = "More Questions..."; textQ.x = 275; textQ.y = 300; textQ.width = textQ.textWidth +20; textQ.selectable = false; sprite1.addChild(textQ); sprite1.buttonMode = true; myCanvas.rawChildren.addChild(sprite1); sprite1.addEventListener(MouseEvent.CLICK, moreQuestions); } var fontSize:int = 12; //text formatting for the displayed question list Begin var qFormat:TextFormat = new TextFormat(); qFormat.font = "Verdana"; qFormat.color = 0x000000; qFormat.size = fontSize; //ending text format for(var t:uint = amt_cnt.start; t&lt;amt_cnt.end; t++){ /*if(t == 0){ var topQ:TextField = new TextField(); topQ.text = full_array[t][1]; mainQsprite.addChild(topQ); }*/ var qSprite:Sprite = new Sprite(); var txt:TextField = new TextField(); txt.defaultTextFormat = qFormat; txt.text = full_array[t][0]; txt.selectable = false; txt.mouseEnabled = false; txt.border = false; txt.width = 500; // how wide you want the text to go. var numLines:Number = Math.floor(txt.textWidth/txt.width)+1; //calculates number of lines of the textfield. txt.height = ((fontSize+8)*numLines); txt.wordWrap = true; qSprite.x = 30; qSprite.y = 350; qSprite.alpha = 0; var temp_a:Number = cache; //20 is the padding between questions displayed if(t != amt_cnt.end-1){ Tweener.addTween(qSprite, {y:temp_a, alpha:1, time:1, delay:t*0.1, transition:"easeoutexpo"}); //tweener INNNNN! }else{ Tweener.addTween(qSprite, {y:temp_a, alpha:1, time:1, delay:t*0.1, transition:"easeoutexpo", onComplete:runTop}); //tweener INNNNN! } cache = txt.height + temp_a; qSprite.buttonMode = true; origArray[t] = new Array(qSprite.x,temp_a, qSprite); mainDict[qSprite] = new Object(); mainDict[qSprite].question = full_array[t][0]; mainDict[qSprite].answer = full_array[t][1]; mainDict[qSprite].count = full_array[t][2]; mainDict[qSprite].top = full_array[t][3]; mainDict[qSprite].origX = qSprite.x; mainDict[qSprite].origY = temp_a; mainDict[qSprite].id = t; mainDict[qSprite].height = txt.height; amt_cnt[t] = new Object(); amt_cnt[t].hit = false; qSprite.addChild(txt); qSprite.addEventListener(MouseEvent.CLICK, clicked); qSprite.addEventListener(MouseEvent.MOUSE_OVER, over); qSprite.addEventListener(MouseEvent.MOUSE_OUT, out); myCanvas.rawChildren.addChild(qSprite); if(full_array[t][3] == true){ var thereIsTop:Boolean = true; } } amt_cnt.array = origArray; /*if(thereIsTop == true){ topAnswer(); //makes the top answer open first thereIsTop = false; }*/ } </code></pre> <p>So this the mainfunction. The top part has the states. main state is loaded first and has the myCanvas canvas. Everything in mainfunction adds to myCanvas.</p> <p>This is my first time working with flex, so tell me if there is a better way of doing this.Thanks?</p> <p>I really need to get this solved. I've been stressing over this for weeks.</p>
