Have Trinidad auto-scroll as myfaces impl has? If rendered output is too long (for example long dataTable) and user clicks a bottom button the page scrolls to the top.
Myfaces have a auto-scroll feature (can be enabled with org.apache.myfaces.AUTO_SCROLL in web.xml). This features saves position of a window between requests and re-scroll it. But it is based on command button rendererer and html form renderer from myfaces. Unfortunately trinidad overrides those renderers so that feature doesn't work. Martin
