HOWTO: Edit nodes in a Flex Tree control

When the node is clicked set editable to false. Set editable to true in the double-click event handler.
// the click event handler 
private function onclick_sourcetree(e:Event):void  {     
    yourTree.editable = false; 
}  

// the doubleclick event handler  
private function ondoubleclick_sourcetree(e:Event):void  {     
    yourTree.editable = true;    
    yourTree.editedItemPosition = {columnIndex:0, rowIndex:sourceTree.selectedIndex}; 
}
