OK, since nobody replied, I solved it myself. Solution is a bit strange, but basically referring to treeData2[0] works to expand the first node, while intuitively you might think that it should be treedData2.node[0]. hmmm...
here's the working code: --- <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute"> <mx:Script> <![CDATA[ [Bindable] private var XLC:XMLList; private function initTree() : void { openTreeNodes(); } private function openTreeNodes():void{ //open the first two folders in IM tree imTree.expandItem(treeData2[0], true, true); trace("treeData2.node[0] = "+treeData2[0]); } ]]> </mx:Script> <mx:XMLList id="treeData2"> <node label="Buddies"> <node label="master" email="[EMAIL PROTECTED]" /> </node> <node label="CoWorkers"> <node label="Ewoldt"/> <node label="Swingler"/> </node> <node label="Offline"> <node label ="Bini" /> </node> </mx:XMLList> <mx:Tree id="imTree" width="100%" height="100%" labelField="@label" showRoot="false" dataProvider="{treeData2}" creationComplete="initTree()"/> </mx:Application> --- In [email protected], "fuad_kamal" <[EMAIL PROTECTED]> wrote: > > I can't get expandItem() to work; anyone see the problem in my code? > I want to automatically expand the first node on the tree. > --- > > <?xml version="1.0" encoding="utf-8"?> > <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; > layout="absolute"> > <mx:Script> > <![CDATA[ > > import mx.events.ListEvent; > > [Bindable] > private var XLC:XMLList; > > private function initTree() : void > { > openTreeNodes(); > } > private function openTreeNodes():void{ > //open the first two folders in IM tree > imTree.expandItem(treeData2.node[0], true, true); > } > ]]> > </mx:Script> > <mx:XMLList id="treeData2"> > <node label="Buddies"> > <node label="master" email="[EMAIL PROTECTED]" /> > </node> > <node label="CoWorkers"> > <node label="Ewoldt"/> > <node label="Swingler"/> > </node> > <node label="Offline"> > <node label ="Bini" /> > </node> > </mx:XMLList> > > <mx:Tree id="imTree" width="100%" height="100%" > labelField="@label" > showRoot="false" dataProvider="{treeData2}" > creationComplete="initTree()"/> > </mx:Application> > -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
