    <p>@Brian Warshaw: This issue happens only about 10-20% of the time. Sometimes it hiccups and simply reloading the app will work fine, other times I will spend half an hour reloading the app over and over again to no avail.</p> <p>This is the original code (when I asked the question):</p> <pre><code>public class BlogReader extends MovieClip { public static const DOWNLOAD_ERROR:String = "Download_Error"; public static const FEED_PARSED:String = "Feed_Parsed"; private var mainXMLLoader:URLLoader = new URLLoader(); public var data:XML; private var _totalEntries:Number = 0; public function BlogReader(url:String){ mainXMLLoader.addEventListener(Event.COMPLETE, LoadList); mainXMLLoader.addEventListener(IOErrorEvent.IO_ERROR, errorCatch); mainXMLLoader.load(new URLRequest(url)); XML.ignoreWhitespace; } private function errorCatch(e:IOErrorEvent){ trace("Oh noes! Yous gots no internets!"); dispatchEvent(new Event(DOWNLOAD_ERROR)); } private function LoadList(e:Event):void { data = new XML(e.target.data); // calculate the total number of entries. for each (var i in data.channel.item){ _totalEntries++; } dispatchEvent(new Event(FEED_PARSED)); } } </code></pre> <p>And this is the code that I wrote based on Re0sless' original reply (similar to some suggestions mentioned):</p> <pre><code>public class BlogReader extends MovieClip { public static const DOWNLOAD_ERROR:String = "Download_Error"; public static const FEED_PARSED:String = "Feed_Parsed"; private var mainXMLLoader:URLLoader = new URLLoader(); public var data:XML; protected var _totalEntries:Number = 0; public function BlogReader(url:String){ mainXMLLoader.addEventListener(Event.COMPLETE, LoadList); mainXMLLoader.addEventListener(IOErrorEvent.IO_ERROR, errorCatch); mainXMLLoader.load(new URLRequest(url)); XML.ignoreWhitespace; } private function errorCatch(e:IOErrorEvent){ trace("Oh noes! Yous gots no internets!"); dispatchEvent(e); } private function LoadList(e:Event):void { isDownloadComplete(); } private function isDownloadComplete() { trace (mainXMLLoader.bytesLoaded + "/" + mainXMLLoader.bytesLoaded); if (mainXMLLoader.bytesLoaded == mainXMLLoader.bytesLoaded){ trace ("xml fully loaded"); data = new XML(mainXMLLoader.data); // calculate the total number of entries. for each (var i in data.channel.item){ _totalEntries++; } dispatchEvent(new Event(FEED_PARSED)); } else { trace ("xml not fully loaded, starting timer"); var t:Timer = new Timer(300, 1); t.addEventListener(TimerEvent.TIMER_COMPLETE, loaded); t.start(); } } private function loaded(e:TimerEvent){ trace ("timer finished, trying again"); e.target.removeEventListener(TimerEvent.TIMER_COMPLETE, loaded); e.target.stop(); isDownloadComplete(); } } </code></pre> <p>I'll point out that since adding the code determining if <code>mainXMLLoader.bytesLoaded == mainXMLLoader.bytesLoaded</code> I have not had an issue - that said, this bug is hard to reproduce so for all I know I haven't fixed anything, and instead just added useless code.</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
