JAI - problem displaying additional pages from multi-page image

Question

Hi,
I have 10 page multipage tiff images. And i would like to show the images one-by-one on a ScrollingImagePanel.
I have a Main frame with two panels. Panel1 which shows the ScrollingImagePanel.
And Panel2 has two buttons. LOAD Button show the 1st page on the ScrollingImagePanel.
And NEXT button is suppose to show the 2nd page and continue until the end of the multipage images.
I am having problem with the NEXT button. I wrote a program that show the page number and page height
on the output screen. It shows the page# and different heights. But it would not show the images on the ScrollingImagePanel.
It just shows the 1st page. I would appreciate if you can help me out with this problom.
Please find the code which is written in JBuilder.
