Sorting problem

[pragya.rawal]

Hi,

I have a DataView and I am sorting data column (on click of column header)
inside it using my custom SortableTaskDataProvider which extends
SortableDataProvider.

So, I pass the property name (column) and DataView (list) and I get the list
sorted on the basis of property.

So, as per the default implementation of compareTo, it sorts Saring starting
with Capital letters first and the the ones that start with lower case.

I require to write a comparator which sorts irrespective of the case (upper
or lower), but the problem I am facing is that the setSort() method provided
by wicket takes the property name.

Is there any way where I can specify that if the property is of type String,
it should sort without considering the case.

Below is my code for SortableTaskDataProvider


public class SortableTaskDataProvider extends
SortableDataProvider<BaseTaskModel> {

    private static final long serialVersionUID = 1L;
    private List<BaseTaskModel> list = new ArrayList<BaseTaskModel>();

    public SortableTaskDataProvider(List<BaseTaskModel> list) {
        super();
        setSort("createdBy", false);
        this.list = list;
    }

    @Override
    public Iterator<? extends BaseTaskModel> iterator(int first, int count)
{
        List<BaseTaskModel> newList = new ArrayList<BaseTaskModel>(list);

        Collections.sort(newList, new Comparator<BaseTaskModel>() {

            @SuppressWarnings("rawtypes")
            @Override
            public int compare(BaseTaskModel o1, BaseTaskModel o2) {
                PropertyModel<Comparable> model1 = new
PropertyModel<Comparable>(o1, getSort().getProperty());
                PropertyModel<Comparable> model2 = new
PropertyModel<Comparable>(o2, getSort().getProperty());

                @SuppressWarnings("unchecked")
                int result =
model1.getObject().compareTo(model2.getObject());

                if (!getSort().isAscending()) {
                    result = -result;
                }

                return result;

            }
        });
        return newList.subList(first, first + count).iterator();
    }

    @Override
    public int size() {
        if (list == null)
            return 0;
        return list.size();
    }

    @Override
    public IModel<BaseTaskModel> model(final BaseTaskModel object) {
        return new AbstractReadOnlyModel<BaseTaskModel>() {
            private static final long serialVersionUID = 1L;

            @Override
            public BaseTaskModel getObject() {
                return object;
            }
        };
    }
}


Any pointers will be highly appreciated.

Thanks,
Pragya
