RE: [flexcoders] Auto-expand Treenodes

[Jonas Windey]

public function expandTree():void { treeTest.selectedIndex = 0; treeTest.expandChildrenOf(treeTest.selectedItem , true); }   Remember to call this function after a validateNow(), so in my case it’s:   treeTest.dataProvider = treeData; treeTest.validateNow();                                                                         expandTree();   Hope this works for you, Jonas   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Sascha Sent: woensdag 27 september 2006 14:03 To: flexcoders@yahoogroups.com Subject: [flexcoders] Auto-expand Treenodes   I know this had been brought up before and I found some stuff on it in the archive but it doesn't work for me... I want to auto-expand a Tree when it is displayed ... objectTree.expandChildrenOf(objectTree.dataProvider[0], true); gives me a "Cannot access a property or method of a null object reference." myTree.selectedItem = myTree.dataProvider.getItemAt(0); //Mailbox node myTree.expandChildrenOf(myTree.selectedItem, true); also doesn't work. objectTree.selectedIndex = 0; objectTree.expandChildrenOf(objectTree.selectedItem, true); Selects the first item but doesn't expand it. What can I do to expand the tree? Any info on this would be appreciated!
