You need a custom datadescriptor if you need to have the tree show a different structure than the underlying xml, but it has nothing to do with expanding nodes.
Are you calling the expandItem using callLater()? ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of hmmmbeer3 Sent: Monday, January 21, 2008 5:57 PM To: [email protected] Subject: [flexcoders] Re: Tree and ITreeDataDescriptor --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > Are you making this harder than it is?

The data is rendered in the Tree perfectly, but I can not get it to visually or programmatically select a node; stepping through the debugger seems to do everything ok (including several expandItem calls), but the tree does not end up visually expanded nor does the selectedIndex value change when selectedItem is changed. Is there anything simple I am missing? I am also more than happy to provide a custom ITreeDataDescriptor, but I need to know how to ask for the children of a tree with no root. Cheers Radek
