title: how to create a text stepper control in flex?
body: <p>I need a control in Flex 3 that is like NumericStepper, but that can display arbitrary strings.  Does this control exist?  If not, what are your suggestions for creating it, or references you would recommend?</p>
  
  <p>For convenience, I'm calling this a TextStepper.  I want this as a compact way to display a list of string choices that a user can cycle through by clicking the up/down buttons.  Compact means no drop-down or pop-up aspects of the control: the only way to change the selected index is to click the up/down button (which updates the text input value).  Value cycling means that I really want to treat the underlying dataProvider as a circular buffer.  So up/down clicks modify selectedIndex in modulo fashion.</p>
