Re: In GWT, ListHandler<List<String>> columnSortHandler does not sort properly

Someone from other forum solved it. So simple!

public int compare(List<String> o1, List<String> o2) {

             

             if (o1 == o2) {

                     return 0;

                   }

                   // Compare the column.

                   if (o1 != null) {

                     int index = verbColumn.getIndex();

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

                   }

                   return -1;

}

But thax you all you guy anyway.

I got these code:

     ListHandler<List<String>> columnSortHandler = new ListHandler<List<String>>(

                    list);

            columnSortHandler.setComparator(nameColumn,

                    new Comparator<List<String>>() {

                      public int compare(List<String> o1, List<String> o2) {

                        if (o1 == o2) {

                          return 0;

                        }

                        // Compare the name columns.

                        if (o1 != null) {

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

                        }

                        return -1;

                      }

                    });

                table.addColumnSortHandler(columnSortHandler);

///****************************/////////////

When sorting column contains iPhone 1, iPhone 2, iPhone 3... then it sorts correctly ie, iPhone 1, iPhone 2, iPhone 3 for ascending & iPhone 3, iPhone 2, iPhone 1 for decending

But when sorting column contains:

1.92 MP 

3.15 MP AF 0.31 MP 

3.2 MP 

5 MP AF and flash 

1.3 MP 

1.3 MP 

2 MP (rear); 0.3 MP (front) 

1.92 MP AF with flash (rear)

it follows no correct order, it didn't even put the 2 "1.3 MP" cell next to each other. The correct order for the above list should be: 

1.3 MP 

1.3 MP 

1.92 MP 

1.92 MP AF with flash (rear) 

2 MP (rear); 0.3 MP (front) 

3.15 MP AF 0.31 MP 

3.2 MP 

5 MP AF and flash

Is there anything wrong with the code above?
