I am trying to use this constructor http://wicket.apache.org/docs/1.4/org/apache/wicket/markup/html/form/CheckBoxMultipleChoice.html#CheckBoxMultipleChoice%28java.lang.String,%20org.apache.wicket.model.IModel,%20java.util.List%29
Here is my best result // Days is an enum and is Serializable List<Day> daysOfWeek = Arrays.asList(Day.values()); CheckBoxMultipleChoice<Day> daysSelector = new CheckBoxMultipleChoice<Day>("daysSelector", *null*, daysOfWeek); But I am not able to generate a suitable model for this constructor (see the *null *parameter ). I found the typing really complex. Can someone can provide an example. Thanks.
