<a href="http://www.rigel222.com/Clip0021.jpg" rel="nofollow noreferrer" title="actual screenshot">alt text http://www.rigel222.com/Clip0021.jpg</a> All I want to do is modify the text value of the XML corresponding to the CURRENTLY SELECTED node in the tree. Everything is a piece of cake except actually changing 'abc' to 'xyz'. <pre><code> [Bindable] public var xml:XML= <rootnode> Content A <parentnode Name="value" Attr2="4"> parent content1 <childnode Name="child" Attr2="fun"> child content </childnode> parent content 2 </parentnode> abc  </rootnode> ; private function XMLTreeLabel(node:Object):String{ if (XMLTree.dataDescriptor.isBranch(node)) { return(node.name()); } else { return(node.valueOf()); } } private function UpdateXMLContent():void { var Node:XML=XMLTree.selectedItem as XML; if ((Node.hasSimpleContent())&& (Node.nodeKind()=="text")&& (Node.valueOf()=="abc")) { Node='xyz' as XML; // I Get To This Line Of Code, // But It Is Impossible To MODIFY // The Value Of The Node // None of these ways work either: // XMLTree.selectedItem=XML('xyz'); // Node=XML('xyz'); // Node.text()[0]='xyz'; // Node.firstChild.nodeValue='xyz'; // Node.setChildren('xyz'); // Node[0]='xyz'; // Is changing the content of xml an unreasonable/impossible // expectation for Flex? } } </code></pre> [... some code omitted...] <pre><code> <mx:Tree height="100%" width="100%" dataProvider="{xml}" labelFunction="XMLTreeLabel" id="XMLTree"></mx:Tree> <mx:Button x="185" y="335" label="Button" click="UpdateXMLContent()"/> </code></pre> P.S. I know I can say xml.rootnode.blahblahblah = whatever, but I need to modify the entry represented in the tree, and therefore cannot hard code the path to the node.

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.
