Class MyFacesStateManager

java.lang.Object
  JspStateManagerImpl
      com.sdm.quasar.client.jsf.application.dialog.MyFacesStateManager

public class MyFacesStateManager

extends JspStateManagerImpl

This class takes care of creating, storing and restoring views (javax.faces.component.UIViewRoot) of dialog instances. It utilizes the dialogs' instance-id to store different view-states for equal view-files (jsp/faces). This is necessary because otherwise all dialog instances (Java objects) would use the same view being stored by the default JSF com.sdm.quasar.client.comp.dlgstate.StateManager as it doesn't know anything about dialog-instances. This class directly extends org.apache.myfaces.application.jsp.JspStateManagerImpl, which is the actual state-manager implementation which is provided by Apache MyFaces.
