Rows state is by row index not row ID unfortunately (I sumbitted an issue on this). As a result you will have that issue. Best thing you can do is write a custom tree state object for your model or manually expand/collapse the paths when you add/remove nodes. BTW - You shouln't have to rebuild the branch, but simply remove the nodes you need to (unless you really need to rebuild the nodes for some reason). -Andrew On 6/17/06, Hughes, Stan <[EMAIL PROTECTED]> wrote: > > > > > This may seem counter-productive to some, but, I need to be able to > dynamically delete and rebuild a tree structure.
