In a demo application I did not enter values for all nodes of submodules. That worked fine, since I never activated these views. When I close the application an exception is thrown, because the system wants to hide the views and creates the views even though they were never activated and therefore created.... The code that does this is this one: SubApplicationView: @Override public void disposed(final ISubModuleNode source) { // not selectable SubModules dont't have an associated view and therefore no view has to be hidden if (source.isSelectable()) { final SwtViewId id = getViewId(source); hideView(id); final SwtViewProvider viewProvider = SwtViewProvider.getInstance(); viewProvider.unregisterSwtViewId(source); } } The Subapplication is called to dispose all SubModuleNode. The method getViewId(source) resolves the viewId and will actually create the view it may never have been activated. It also fails if there is no such view Id for a specific node is defined in the assembly for Rapid Prototyping. The exception is this: org.eclipse.riena.navigation.ApplicationModelFailure: viewId is null for nodeId NavNodeId:riena.demo.Addressescommunication.submodule[null] at
