> Key: PIVOT-1037
> URL: https://issues.apache.org/jira/browse/PIVOT-1037
> Project: Pivot
> Issue Type: Bug
> Components: wtk-terra
> Reporter: Roger Whitcomb
> Assignee: Roger Whitcomb
> Priority: Minor
>
> We build a tree, but don't expand it all initially. User can do things that
> cause the tree to be rebuilt before the child nodes have become visible.
> This leads to exceptions such as:
> java.lang.IndexOutOfBoundsException: Index 1 out of bounds [0,0].
