             Project: Apache Flex
          Issue Type: Bug
          Components: Spark: TextArea
    Affects Versions: Adobe Flex SDK 4.6 (Release)

Resizing a Spark TextArea with a TextFlow component's height rapidly, down to 0 results in
a null object reference. (prevLine at line number 3018 is null)

Error details:

Error #1009: Cannot access a property or method of a null object reference.
