I spent about 2 hours trying to figure out why one of my lists that was working in a sandbox page did not render at all in another scene and I finally figured it out. I thought I would share it here to save someone else the trouble.

If you set disableSceneScroller=true on the scene arguments when you push a scene, it disables the scroller and prevents rendering. I had assumed from reading the Palm developer information here that it just disabled scrolling, not the rendering of the list:

"The scroller widget is used to provide all scrolling behavior. By default, each scene contains a Scroller widget. You can disable this default behavior by having a truthy value in the disableSceneScroller property in the scene arguments to pushScene). The Scroller widget can also be instantiated anywhere else in the scene. The framework will automatically update the position of itself with respect to the screen."
