Problem with Column .getValue(T object) in CellTable.

Hi guys,

I am trying to add a Column using TextInputCell into a CellTable. The code is like below:

//the display data class:

public class Foo {

  ...

  //the field to be used in CellTable 

  int quantity;

  ...

  //setters and getters...

  public int getQuantity() {

    return quantity;

  }

  public void setQuantity(int quantity) {

    this.quantity = quantity;

  }

  ...

}

//In the entry point onModuleLoad():

CellTable<Foo> cellTable = new CellTable<Foo>();

final ListDataProvider<Foo> dataProvider = new ListDataProvider<Foo>();

Column<Foo, String> quantityCol = new Column<Foo, String>(cell) {

  @Override

  public String getValue(Foo object) {

    //format the integer with MyFormatter to add thousand separators. 

    //e.g. 1000 -> 1,000

    return MyFormatter.addSeparator(object.getQuantity());

  }

};

quantityCol.setFieldUpdater(new FieldUpdater<Foo, String>() {

  @Override

  public void update(int index, Foo object, String value) {

    

    // remove thousand seperator, e.g. 1,000 -> 1000

    // and set it back to the object.

    object.setQuantity(MyFormatter.removeSeparator(value));

    //to refresh the display.

    dataProvider.refresh();

  }

});

//add this column to cellTable

cellTable.addColumn(quantityCol, "Quantity");

//adds cellTable to the dataProvider.

dataProvider.addDataDisplay(cellTable);

//adds it to the RootPanel.

RootPanel.get().add(cellTable);

//creates a data object, and push it into dataProvider to display.

Foo foo = new Foo();

foo.setQuantity(1000);

dataProvider.getList().add(foo);

Problem: 

The cellTable correctly shows a formatted value 1,000 in the TextInputCell after the page finished its loading.

After I input a value, e.g. 100000. the TextInputCell remained its display 100000, rather than displaying a formatted value 100,000.

I have debugged that getValue(Foo object) did get invoked after dataProvider.refresh(), and its return value is as correct as 100,000.

I have tried using cellTable.redraw() instead of dataProvider.refresh(). It does not work either.

The GWT version I am using is 2.5.0 release.

Does anyone know why the TextInputCell never gets updated accordingly after Column.getValue(T object), or whether this is the right solution to use cases like above?
