The problem with adding pages to the sliding panel are potential performance issues if you start to add too many pages… that’s why the sliding panel has no “addPage” method. What we advise is rather to have a third page where you would dynamically change the content.
i solved how to add panels, but than very slow became scrollers. everytime i change content i disable old scroller and assign new, because on htc desire other methods to reset scroller doesn’t work. So, its not posible to use many sliding panels with scrollers and dynamic content.
