My code follows.</p> <pre><code>for(var i = 0; i &lt; listBox.selectedIndices.length; i++) { var toRemove = listFiles.selectedIndices[i]; dataArray.splice(toRemove, 1); } </code></pre> <p>Thanks in advance!</p> <p><strong>Edit</strong> Here is my swf. The Add Photos works except when you remove items. <a href="http://www.3rdshooter.com/Content/Flash/PhotoUploader.html" rel="nofollow noreferrer">http://www.3rdshooter.com/Content/Flash/PhotoUploader.html</a></p> <ol> <li>Add 3 photos different.</li> <li>Remove 2nd photo.</li> <li>Add a different photo.</li> <li>SWF adds the 2nd photo to the end.</li> </ol> <p>Any ideas on why it would be doing this?</p> <p><strong>Edit 2</strong> Here is my code</p> <pre><code>private function OnSelectFileRefList(e:Event):void { Alert.show('addstart:' + arrayQueue.length); for each (var f:FileReference in fileRefList.fileList) { var lid:ListItemData = new ListItemData(); lid.fileRef = f; arrayQueue[arrayQueue.length]=lid; } Alert.show('addcomplete:' + arrayQueue.length); listFiles.executeBindings(); Alert.show(ListItemData(arrayQueue[arrayQueue.length-1]).fileRef.name); PushStatus('Added ' + fileRefList.fileList.length.toString() + ' photo(s) to queue!'); fileRefList.fileList.length = 0; buttonUpload.enabled = (arrayQueue.length &gt; 0); } private function OnButtonRemoveClicked(e:Event):void { for(var i:Number = 0; i &lt; listFiles.selectedIndices.length; i++) { var toRemove:Number = listFiles.selectedIndices[i]; //Alert.show(toRemove.toString()); arrayQueue.splice(toRemove, 1); } listFiles.executeBindings(); Alert.show('removecomplete:' + arrayQueue.length); PushStatus('Removed photos from queue.'); buttonRemove.enabled = (listFiles.selectedItems.length &gt; 0); buttonUpload.enabled = (arrayQueue.length &gt; 0); } </code></pre>

    1. COWhat's wrong with the code you're using? Does 'splice' not work for you?

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.
