RE: [flexcoders] Re: Flex 2b3 - Tree Problems
Michael, thanks for the tree suggestions.
To resolve the issue I had to add the @label along withthe showRoot = falseattribute on the tree control. I have included example code for others that may be experiencing tree problems.
Josh
mx:Tree id="menuItemsTree" labelField="@label" showRoot="false"/
//Note menu is a ArrayColleciton from a remoteObject that returns the XML as a single stringcalled menu_xml_string
public static function formatMenuXmlForTree(menu:ArrayCollection):XMLDocument{ var menuXMLDocument:XMLDocument = new XMLDocument();menuXMLDocument.parseXML(menu.getItemAt(0).menu_xml_string);menuItemsTree.dataProvider = menuXMLDocument;}
Sample XML?xml version="1.0" encoding="utf-8"?menuitems menuitem menuID="70" label="Letters" menuitem menuID="71" label="A" / menuitem menuID="72" label="B" / menuitem menuID="73" label="C" / /menuitem menuitem menuID="74" label="Numbers" menuitem menuID="75" label="1"/ menuitem menuID="75" label="2"/ menuitem menuID="75" label="3"//menuitem/enuitems

Re: [flexcoders] Re: Flex 2b3 - Tree Problems
I wanna learn to my own impl of ITreeDataDescriptor.
May I have your sample code, if you enable to me?
