    <p>I handle similar cases by storing the original data in an XML property of the Value Object ("VO"), and reset all of the other property values when the VO is needed.</p> <p>So, when it is first needed to be viewed, I go get the XML:</p> <pre><code>&lt;Node&gt; &lt;prop1&gt;value&lt;/prop1&gt; &lt;prop2&gt;value&lt;/prop2&gt; &lt;prop3&gt;value&lt;/prop3&gt; &lt;prop4&gt;value&lt;/prop4&gt; &lt;/Node&gt; </code></pre> <p>When I retrieve the XML, in my result handler, the first thing I do is create an instance of my VO, and set the XML property, and then call a public function in a separate class to set the VO's properties:</p> <pre><code>private function getNodeResultHandler(event:ResultEvent):void { var myNode:Node = new Node(); myNode.xmlData = new XML(event.result); nodeUtils.setNodeProperties(myNode); } public class nodeUtils { public function setNodeProperties(node:Node):void { var nodeXmlData:XML = node.xmlData; myNode.prop1 = nodeXmlData.prop1; myNode.prop2 = nodeXmlData.prop2; myNode.prop3 = nodeXmlData.prop3; myNode.prop4 = nodeXmlData.prop4; } } </code></pre> <p>Then, any time you switch your view to edit mode, you call that same function to reset the properties to the values stored in the XML.</p> <p>The only other thing you need to do is reset that XML any time the user commits changes to the VO. I usually handle this by passing back the VO's data in the same format on a Save and Get, and then saving the XML just as above.</p> <p>I usually do this in a Cairngorm MVC application, so I have event/command chains to handle all of this, but you can put this functionality in any number of classes, or in the VO class itself, whichever is easiest for you to maintain.</p>

    1. COThanks for your input! It's good to see how other have handled similar situations. In my case, the XML object is a DTO, but I'd rather not maintain a reference to it on my model object. However, storing the DTO and implementing a "reset" method somewhere is probably how I will end up dealing with this. I'll revisit this question once it's been implemented.

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.
