A not terribly catchy acronym for the "Render Single Javascript Call in <script>" (RSJCIS) strategy used in RSF to initialise autonomous markup segments on the client with Javascript event handlers etc. This is used in contrast to the more widespread technique based on manipulating {{body onload=""}} handlers in view of its greater portability to other deployment environments such as JSR-168 portlets. Much more discussion on this issue is on the [BuildingRSFComponents] page.
