How's this look?

@Name("org.jboss.seam.ui.ObjectConverter")
  | @Scope(PAGE)
  | @Install
  | @Converter(forClass=Object.class)
  | @BypassInterceptors
  | public class ObjectConverter implements javax.faces.convert.Converter, Serializable {
  | 
  | 	private Map<String, Object> objects;
  | 
  | 	@Create
  | 	public void create() {
  | 		objects = new HashMap<String, Object>();
  | 	}
  | 
  | 	public String getAsString(FacesContext facesContext, UIComponent cmp, Object value) throws ConverterException {
  | 		if(value == null)
  | 			return null;
  | 		
  | 		for(Map.Entry<String,Object> entry: objects.entrySet())
  | 			if(entry.getValue() == value)
  | 				return entry.getKey();
  | 		
  | 		if(facesContext.getApplication().getStateManager().isSavingStateInClient(facesContext)
  | 				&& Seam.isEntityClass(value.getClass()))
  | 			throw new ConverterException("ObjectConverter is unable to handle entity classes when client-side " +
  | 					"state saving is enabled. Please use EntityConverter instead, or enable server-side state saving");
  | 		
  | 		String key = new UID().toString();
  | 		objects.put(key, value);
  | 		
  | 		return key;
  | 	}
  | 
  | 	public Object getAsObject(FacesContext facesContext, UIComponent cmp, String key) throws ConverterException {
  | 		if (key == null)
  | 			return null;
  | 
  | 		return objects.get(key);
  | 	}
  | 	
  | }
