Well, you can either implement StateHolder and restore the values in
restoreState or implement readObject() and relink them there using
code like this.
FacesContext facesContext = FacesContext.getCurrentInstance();
setShopContext(facesContext.getApplication()
.getVariableResolver().resolveVariable(facesContext, "prShopContext"));
