-------------------------------------
Summary: Removing tree nodes before they are visible will cause
exceptions
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
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].
