Re: Sorting using a DataTable

Hello,
I am using a SortableDataProvider with a DefaultDataTable.
From my understanding, it seems that for every column that I wish to sort
on, I need to add code to the iterator method of the
data provider. None of the columns were sorting and when I added some code
in the iterator method (see below) I was able to sort on the street column.
Is this the best way to sort columns? I am using wicket 1.3.
it might be better to use that sorting info to get the data from the db in the
right sort order.
Thanks Karen
iterator method from a SortableDataProvider
public Iterator iterator( int first, int count ){
final SortParam sp = getSort();
EventList list = getInterruptionList();
if ( sp.getProperty().equals(street) ){
Collections.sort(list, new Comparator()
{
public int compare(Object arg0, Object arg1){
if ( sp.isAscending() )
return
((Interrupt)arg0).getStreet().compareTo(((Interrupt)arg1).getStreet());
else
return
((Interrupt)arg1).getStreet().compareTo(((Interrupt)arg0).getStreet());
}
});
}
return list.listIterator( first );

Re: Sorting using a DataTable
usually sorting is done in the database. if you get that list outside
the database, then yes, you have to sort it using your own
comparators.
