Anyone had experience using the tree widget to render mixed structures? I have a layout something like this --

...

...

> Folder Folder XML Folder XML Folder XML Folder XML Folder Folder Folder

and so forth. I'd like to point the tree widget at the top level folder and have it render a set of stuff. When an XML (ParsedXML) folder is encountered, the branches method has to be different. (That was the effort of the day, getting tpValues to ignore implementation nodes. I did it by brain surgery on the Package source--a decision that will certainly come back to haunt me.) Presumably, the way to make it work is to use branches-expr and toggle between a folderish objectValues and a ParsedXML-ish tpValues. Anyone had any experience doing this? -d
