---------------------------------------------------------------
So, I *think* a lot of the problem is that the "monitorBranch" is not called
until/unless either "setBranchExpanded" or some form of "setSelectedPath" is
called, or a node's checked state changes, which is why the workaround works
(from "setBranchExpanded"), and/or when the branch is expanded/contracted after
the beginning, everything works. But (right now, with some fixes applied), the
first "Remove" after the "Add" doesn't appear to do anything unless you
expand/contract the node first, and so you get errors trying to click on the
"new branch" which is not really there anymore.

> Key: PIVOT-734
> URL: https://issues.apache.org/jira/browse/PIVOT-734
> Project: Pivot
> Issue Type: Bug
> Components: wtk-terra
> Affects Versions: 2.0
> Reporter: Brent N Atkinson
> Assignee: Roger Whitcomb
> Priority: Minor
> Fix For: 2.5
>
>
> When showEmptyBranchControls is false, adding items to empty branch nodes
> does not cause the UI to include branch controls for the now non-empty branch.
> Using the definition:
> {code}
> <TreeView bxml:id="aTree" styles="{showEmptyBranchControls:false}">
> ...
> </TreeView>
> {code}
> ...adding an item to an empty branch in the tree's data exposes the problem.
> The expected behavior is that the node reflects that it is non-empty and the
> expander controls show up. The actual behavior is that there is no change in
> the controls for the node.
> See the user-list thread for details:
