GXT 1.2.3 : Sort Dates in Grid

[91dj85]

In a Grid, I have a column "Date", and when I want to sort this column, the dates sort correctly in host mode but do not sort correctly with Firefox or IE.


It was OK with version 1.1.1 but not with 1.2.3.

for me work fine

look http://www.extjs.com/explorer/#editablegrid

post the code example

public class NewTabItem extends TabItem {

    private GroupingStore<BaseModel> gridStore;

    public NewTabItem (List<BaseModel> dates) {
        super();

        List<ColumnConfig> columns = new ArrayList<ColumnConfig>();
        ColumnConfig date = new ColumnConfig("Date", "Released", 80);
        date.setDateTimeFormat(DateTimeFormat.getFormat("MMMM dd, yyyy"));
        columns.add(date);

        final ColumnModel cm = new ColumnModel(columns);

        final GroupingView view = new GroupingView();
        view.setForceFit(true);
        view.setGroupRenderer(new GridGroupRenderer() {
            public String render(GroupColumnData data) {
                String l = data.models.size() == 1 ? "Item" : "Items";
                return data.group + " (" + data.models.size() + " " + l + ")";
            }
        });

        gridStore = new GroupingStore<BaseModel>();
        gridStore.add(dates);

        Grid grid = new Grid<BaseModel>(gridStore, cm);
        grid.setLoadMask(true);
        grid.setBorders(true);
        grid.setView(view);

        setLayout(new FitLayout());
        setStyleAttribute("margin", "8px 0 0 0");
        add(grid);
    }

}

work fine in host mode, but not in firefox or IE.
see image : (Dates are sorted in DESC...)

look http://extjs.com/deploy/gxtdocs/com/...eTimeFormat%29 test with this

[91dj85]

Sorry, it's DateTimeFormat.getFormat("MMMM dd, yyyy"); in my code
but it's not the problem. The result is the same.

[MikeS]

Same problem for me.
Have a column configuration with DateTimeFormat specified.
Grid sorts it as a string rather than a date

GXT 1.1.1 :
- Host mode : OK
- IE : OK
- Firefox : OK

GXT 1.2.3 :
- Host mode : OK
- IE : ERROR
- Firefox : ERROR

With the same code for 1.1.1 and 1.2.3



WHY ?

I am having the same issue in GXT 2.0.1. Did you ever get this resolved?

[Kroywen]

Looks like a GWT bug

http://code.google.com/p/google-web-...00&q=compareto

Basic issue is that the compareTo method in java.sql.Timestamp is broken. If you are returning Timestamp objects from the backend you will run into this issue.

We wound up creating our own local copy of the emulated Timestamp class and changing the compareTo method to

  
  public int compareTo(Timestamp o) {
    /*
    int delta = (int) (getTime() - o.getTime());
    return delta == 0 ? getNanos() - o.getNanos() : delta;
    */
    int i = super.compareTo(o);
    if (i == 0) {
      if (getNanos() > o.getNanos()) {
        return 1;
      } else if (getNanos() < o.getNanos()) {
        return -1;
      }
    }
    return i;
  }
