Subject [jira] [Comment Edited] (PIVOT-734) Branch controls do not update while showEmptyBranchControls=false

---------------------------------------------------------------

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.

>             Project: Pivot
>          Issue Type: Bug
>          Components: wtk-terra
>    Affects Versions: 2.0
>            Reporter: Brent N Atkinson

>            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.
