Subject: multi frame image viewer not updating

Hi.  I'm relatively new to FXRuby, and Ruby in general, so hopefully I
have just overlooked something simple.  I am making a program that has a
image viewer on one side that shows multiple jpg's in a vertical frame.
Unfortunately, when I attempt to change the images in the viewer,
nothing happens.  I'll post the relevant code.  I may make a type in the
generalization of it, so if you spot one, that's not the solution:

(somewhere in a FXMainWindow class)
@stackViewerWindow = FXScrollWindow.new(@stackViewerFrame,
  LAYOUT_FILL_X|LAYOUT_FILL_Y)
@stackViewer = FXVerticalFrame.new(@stackViewerWindow,
  LAYOUT_FIX_WIDTH|LAYOUT_FILL_Y, 0, 0, 357)
@pButton2.connect(SEL_COMMAND) do
  @stackViewer = FXVerticalFrame.new(@stackViewerWindow,
    LAYOUT_FIX_WIDTH|LAYOUT_FILL_Y, 0, 0, 357)
  random_object.display(theApp, @stackViewer)
end

(in some random_object class)
  def display(theApp, target)
    number = @cards.length
    image = Array.new
    imageView = Array.new
    number.times do |number|
  filename= @cards.at(number).card_id.to_s + ".jpg"
  image[number] = FXJPGImage.new(theApp, nil,
    IMAGE_KEEP|IMAGE_SHMI|IMAGE_SHMP)
  FXFileStream.open(filename, FXStreamLoad) do |stream|
    image[number].loadPixels(stream)
  end
  image[number].create
  imageView[number] = FXImageFrame.new(target, image[number])
    end
  end

Thanks for your help in advance!
