Igor Vaynberg resolved WICKET-2364.
-----------------------------------

       Resolution: Fixed
    Fix Version/s: 1.5-M1
                   1.4.4
         Assignee: Igor Vaynberg

after looking at your patch i decided to go with the simpler option of making setobject() work, the alternative adds too much complexity

>             Project: Wicket
>          Issue Type: Improvement
>          Components: wicket
>    Affects Versions: 1.4-RC6
>            Reporter: Michael Mikhulya
>            Assignee: Igor Vaynberg
>             Fix For: 1.4.4, 1.5-M1

> To keep it compatible with current usage:
> public final void setObject(Object obj) {
>     reload(obj);
>     tempModelObject = obj;
> }
> protected void reload(Object obj) {
>     throw new OperationNotSupportedException("Read only model");
> }
> Subclasses can now implement their own write logic. This is necessary for for instance stand alone dropdownchoice components that need to store their selection.
> e.g.
> MyPage {
>     IModel<SchoolYear> selectedSchoolYear;
>     public MyPage() {
>         selectedSchoolYear = new HibernateModel<SchoolYear>(SchoolYear.current());
>         new SchoolYearDropDownChoice(this, "schoolyear", selectedSchoolYear);
>     }
> }
> If HibernateModel is not writeable then the selected SchoolYear instance would end up in the session.
