The function with the removeChild problem is ClearMsg.


I have a custom function that doesn't function correctly the first time the function executes it removes a textFiled from the display list without a problem but the second time that it executes it won't remove a second textfield and I don't know why here is the code from the time the textField is added to the diplay list to where its deleted.....Btw the function in question is being executed by a custom event listener.....the errors i receive are TypeError: Error #1009: Cannot access a property or method of a null object reference...Also note that i can remove the textField in question from any function other thatn the one the custom event executes....the custom event function is the problem....anybody have a solution?....also keep in mind that every go around the whole class is called again so all the  msgTa = newTextFeild are called repeatedly.

Plz let me know if you need furthur clarification.

sendBtn.addEventListener(MouseEvent.CLICK, sendMsg0,false,0,true); 
            msgOut.addEventListener(KeyboardEvent.KEY_DOWN, sendMsg1,false,0,true); 
            comboBox.addEventListener(Event.CHANGE,chFontSize,false,0,true); 
            call4.addEventListener("TYPE_UID", onUserID,false,0,true); 
            reconnect1.addEventListener("TYPE_CMSGTA", ClearMsg,false,0,true); 
             
            msgTa.addEventListener(MouseEvent.MOUSE_WHEEL,Wheel,false,0,true); 
            msgTa.addEventListener(Event.SCROLL, scrolls,false,0,true); 
            scrollBar.addEventListener(MouseEvent.MOUSE_OVER,StopScroll,false,0,true); 
            scrollBar.addEventListener(MouseEvent.MOUSE_OUT,StartScroll,false,0,true); 
            msgTa.addEventListener(MouseEvent.MOUSE_OUT,StartScroll,false,0,true); 
            addEventListener(MouseEvent.CLICK,clickHandler);           
             
             
            if ( rePublishID!=1&&rePublishID1!=2) { 
                addChild(msgTaCon); 
                msgTaCon.addChild(msgTa); 
                insID=msgTa; 
                 
                 
            } 
            if (rePublishID1 ==1) { 
                addChild(msgTaCon); 
                msgTaCon.addChild(msgTa1); 
                insID=msgTa1; 
                 
            } else if (rePublishID1 ==2) { 
                addChild(msgTaCon); 
                msgTaCon.addChild(msgTa); 
                insID =msgTa; 
                 
            } 
             
        } 
        private function ClearMsg(e:ClearMsgTa):void { 
          
            if (e.num10[0]==1) { 
                    while( msgTaCon.numChildren > 0 )msgTaCon.removeChildAt( 0 ); 
                    while( chatCon.numChildren > 0 )chatCon.removeChildAt( 0 ); 
                    chatCon.parent.removeChild(chatCon); 
                    msgTaCon.parent.removeChild(msgTaCon); 
                    scrollBar.parent.removeChild(scrollBar); 
                    chatCon=null; 
                    msgTaCon =null; 
                    scrollBar=null; 
                     
                     
            } 
         
            if (e.num10[0]==2) { 
            msgTaCon.removeChild(msgTa1); 
            msgTaCon = null; 
        } 
    }

Sounds like you're trying to remove a display object that isn't there. Find out where it's causing it and run a simple trace before you remove it to make sure it's not null.
