Re: columnSortHandler on a Dynamic CellTable

Thank you very much!

Hi everybody,

I create a dynamic CellTable this way:

for (int column = 0; column < arrListFilters.size(); column++) {
IndexedColumn IColumn= new IndexedColumn(column);
IColumn.setSortable(true);
table.addColumn(IColumn, arrListFilters.get(column));
}

final ListDataProvider<List<String>> provider = new ListDataProvider<List<String>>(rows);
provider.addDataDisplay(table);

for (String row: rowsArray) {
rows.add(Arrays.asList(row));}

It works well, but I want to add comparator to my table. So I do that, but it doesn't work:

ListHandler<List<String>>(rows); 

i=0;
while(i<table.getColumnCount()){
columnSortHandler.setComparator(table.getColumn(i),
new Comparator<List<String>>() {
public int compare(List<String> o1,List<String> o2) {
        if (o1 == o2) {
return 0;
}
 if (o1 != null) {
return (o2 != null) ? o1.get(0).compareTo(o2.get(0)) : 1;
} 

                                    }
});
i=i+1;
}

 

table.addColumnSortHandler(columnSortHandler);

i=0;
while(i<table.getColumnCount()){
table.getColumnSortList().push(table.getColumn(i));
i=i+1;
}

I know that the problem is here, but I don't know how to what I want.

 if (o1 != null) {

return (o2 != null) ? o1.get(0).compareTo(o2.get(0)) : 1;

}  

Any ideas?

Thanks a lot!
