Andrew,
Thanks for the response, but, if I could ask just one other thing...
I have tried a couple of things to collapse the node as I re-add it,
but, it doesn't seem to do anything. Can you give some hint as to how I
do this?
This is what I tried (n00b alert)
TreeNodeBase tnb = new
TreeNodeBase(fi[i].getType(),fi[i].getName(),true);
tnb.setIdentifier(fi[i].getPuid());
TreeModelBase tm = new TreeModelBase(tnb);
TreeState ts = tm.getTreeState();
if (ts.isNodeExpanded(fi[i].getPuid()))
ts.toggleExpanded(fi[i].getPuid());
selectedNode.getChildren().add(tnb);
I know this is wrong, but, I am not sure why...
Looking at the issue you posted, you refer to a TreeNode.getNodeId(). I
am using Tomahawk 1.1.1 and I do not have this function...
Also, I have looked at the Wiki, the FAQ, the javadocs and this list but
find myself still needing some explanation on some of the Tomahawk
functions. Are there any other resources you can point me to?
Thanks,
Stan

Subject: Re: Deleting Nodes/Branch from Tree
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).
