Subject [jira] [Created] (PIVOT-1028) When SuggestionPopup data changes and an item beyond the new length was highlighted, an IndexOutOfBounds is thrown

Roger Whitcomb created PIVOT-1028:
-------------------------------------

             Summary: When SuggestionPopup data changes and an item beyond the new length
was highlighted, an IndexOutOfBounds is thrown
                 Key: PIVOT-1028
                 URL: https://issues.apache.org/jira/browse/PIVOT-1028
             Project: Pivot
          Issue Type: Bug
          Components: wtk-terra
    Affects Versions: 2.0.5, 2.1
            Reporter: Roger Whitcomb
            Assignee: Roger Whitcomb
             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.

Here is a (partial) stack trace:

java.lang.IndexOutOfBoundsException: Index 1 out of bounds [0,0].
