Use PayLayoutBean.setDocumentFilename(String) instead and it will fire the IPageLayoutControlEventsOnPageLayoutReplacedEvent event.To test this case, run the MapViewer sample that is included in the Engine Developer Kit.At line 146 of MapViewerFrame.java, it calls the loadMxFile(String, Object) method. Therefore, the overview map is not updated when the application first load. It is because the IPageLayoutControlEventsOnPageLayoutReplacedEvent event is not fire which sets the overview map.
