    <p>The idea with my setup is that I have an input text field and three separate buttons on stage. When you type something in the text field and press the input button, the text inside the field is added to an array. </p> <p>When you press the display button the contents of the array are displayed on screen (each value of the array is displayed underneath the last value). </p> <p>The final button is supposed to remove all the current values on the array, and clear all displayed values on screen. But I cannot get my code to work as intended, since I receive, </p> <p><code>TypeError: Error #1009: Cannot access a property or method of a null object reference.</code> </p> <p>With this block of code:</p> <pre><code>import flash.text.TextField; import flash.events.MouseEvent; var myArray:Array = new Array (""); var tf:TF; btnInput.addEventListener(MouseEvent.CLICK, txtInput); function txtInput(event:MouseEvent):void {myArray.push(txtInput.text);} btnDisplay.addEventListener(MouseEvent.CLICK, txtDisplay); function txtDisplay(event:MouseEvent):void {for (var i:int = 0; i &lt; myArray.length; i++) {var tf:TF = new TF(); tf.txt.text = myArray[i]; tf.y = 280 + (i * 25); tf.x = 265; addChild(tf); tf.name="test";} } btnClear.addEventListener (MouseEvent.CLICK, txtClear); function txtClear(event:Event){ myArray.splice(1); if (tf.numChildren != 0){ removeChild(getChildByName("test"));} } </code></pre> <p>Alternatively, when I add</p> <pre><code>var tf:TF = new TF; </code></pre> <p>It removes only one displayed value on screen. Also I might add, that "TF" is a movie clip in the library that contains a dynamic text field that's instance name is txt. Is the problem only with the last button, or should I change something else as well? I don't know how to make this work as I want it to. I'm pretty new to coding so any tips or help would be much appreciated. Thanks in advance!</p>

    1. COYou have an array of values, and not have an array of TFs? Rework this ASAP, your 1009 will likely disappear entirely.

    2. COtf is a movieClip symbol TF. How do I put them in an Array? myArray is for input text. So I have string in array. I don't understand what you mean by putting TF's in array, too.

    3. COAdd another array that will hold those TFs. It's as easy as with strings, `tfArray.push(tf);` and then reference them from there, including removing in bulk.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
