>                 URL: https://issues.apache.org/jira/browse/PIVOT-1028
>             Project: Pivot
>          Issue Type: Bug
>          Components: wtk-terra
>    Affects Versions: 2.1, 2.0.5
>            Reporter: Roger Whitcomb
>            Assignee: Roger Whitcomb
>            Priority: Minor
>             Fix For: 2.1
>
>
> One way to reproduce is to have a long SuggestionPopup list of suggestions, then move the mouse to a selection down in the list, so it is highlighted, then type something in the attached TextInput so that the list is shorter, then move the mouse out of the suggestion list:  an IndexOutOfBoundsException will be thrown with the error being the old "highlightIndex" of TerraListViewSkin being out of range of the new list data length.
> Appears to only happen if "variableItemHeight" is set true, which shouldn't be the normal case.
