What kind of data provider are you giving it? Couldn't you implement your
own ISortableDataProvider?
ISortableDataProvider<Post> dp = new SortableDataProvider<Post>() {
public Iterator<? extends Post> iterator(int first, int count) {
// TODO Auto-generated method stub
// use this property to determine if that's the column
selected. then sort by it
getSort().getProperty();
return null;
}
public IModel<Post> model(Post object) {
return new DBObjectDetachableModel<Post>(object);
}
public int size() {
// TODO Auto-generated method stub
return 0;
}
};
