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.
