JSF Inject multiple beans into a backing-bean - spring

Question

I'm injecting two beans inside my backing bean with ManagedProperty. The backing bean is view scope and the model bean is request scope that looks like this:
#ManagedBean(name = "categoryBB")
#ViewScoped
public class CategoryBackingBean implements Serializable {
private static final long serialVersionUID = -880184144170934066L;
private static final Logger LOG = Logger
.getLogger(CategoryBackingBean.class);
#ManagedProperty("#{categoryService}")
CategoryService categoryService;
#ManagedProperty("#{categoryBean}")
CategoryBean categoryBean;
//Getters/Setters...
}
However I'm receiving the following error:
javax.servlet.ServletException: Unable to create managed bean categoryBB.
The following problems were found:
The scope of the object referenced by expression #{categoryBean}, request, is shorter than the referring managed beans (categoryBB) scope of view
