Hi Ryan, Thanks. It seems data decriptor is only for reading properties, not changing.
Actually I think my problem is common, for example: <Folder lable="1"> <file name="file1.txt"/> <Folder lable = "1.1"/> </Floder> In the xml above, node named "Folder" should be always displayed as a branch. However, the default of flex tree is, if the node doesn't have sub nodes, display it as leaf. So the question comes up, how to set "isBranch" property base on node names? Thanks a lot. --- In flexcoders@yahoogroups.com, "Ryan Frishberg" <[EMAIL PROTECTED]> wrote: > > Check out dataDescriptor.
