Simple solution to a simple problem:
in form constructor:
List selectionList = new ArrayList();
selectionList.add("Mand");
selectionList.add("Kvinde");
gender = new DropDownChoice("gender", new Model(new String()),
selectionList);
add(gender);
onSubmit() :
int genderPojo = Integer.parseInt(gender.getValue()); // Index on
selected item in dropdown
member.setGender(genderPojo == 0 ? 1:2); // Convert gender to
int in pojo
