RE: [flexcoders] Auto-expand Treenodes

[Sascha]

Thanks a lot Jonas, I wasn’t sure the Validation is necessary here!  Since my Tree has several root nodes I changed the code to open all of the nodes …   for each (var o:Object in objectTree.dataProvider) {        objectTree.expandChildrenOf(o, true); }     Works like a charm! Thanks again!

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!
