DatePickerCell's change skips one checkBox row selection/unselection but same works for next check/unchecks

Hello experts,

I have followed this example and have added a column with a cell, DatePickerCell for a DataGrid.

Using gwt 2.7.0.

Before the DatePickerCell's value is changed I check for the row selection, if row is a selected one I would make the change otherwise restore the old date.

Two cases:

1. Current state: checkBox is unchecked, hence the row is an unselected row:

- on change of the DatePickerCell, I throw a message to select the row first and restores the old date

- after this when I click on checkBox, it gets checked but the row does not get selected (on this first click)

- next when I click the checkBox again (for the 2nd time now), it does not get unchecked but the row gets selected

 

2. Current state: checkBox is checked, hence the row is a selected row:

- on change of the DatePickerCell, the change is accepted

- after this when I click on the checkBox, it gets unchecked but the row does not get unselected (on this first click)

- next when I click the checkBox again (for the 2nd time now), it does not get checked but the row gets unselected

For other columns with EditTextCell cell the checkBox row selection is working fine.

How to fix this?

The selection model (a multiple selection model) code and checkBox column code is followed as is given in the link (example)

Pasting below code which I have used to add a column with DataPickerCell:

DateTimeFormat dateFormat = DateTimeFormat.getFormat( PredefinedFormat.DATE_MEDIUM );

final Column<InterfaceTableRow, Date> fromIntOwnConcDateColumn = new Column<InterfaceTableRow, Date>(new DatePickerCell(dateFormat)) {

@Override

public Date getValue(InterfaceTableRow object) {

return object.getFromInterfaceOwnerConcurrenceDate();

}

};

// set sortable

fromIntOwnConcDateColumn.setSortable(true);

// set own comparator

sortHandler.setComparator(fromIntOwnConcDateColumn, new Comparator<InterfaceTableRow>() {

@Override

public int compare(InterfaceTableRow o1, InterfaceTableRow o2) {

return o1.getFromInterfaceOwnerConcurrenceDate().compareTo(o2.getFromInterfaceOwnerConcurrenceDate());

}

});

// add to dataGrid

dataGrid.addColumn( fromIntOwnConcDateColumn, InterfaceTableRow.COL_NAME_FROM_INT_OWNER_CONC_DATE );

// field updater

fromIntOwnConcDateColumn.setFieldUpdater(new FieldUpdater<InterfaceTableRow, Date>() {

@Override

public void update(int index, InterfaceTableRow object, Date value) {

// called when the user changes the value

// check if the object is selected i.e. the check box is checked

if( selectionModel.isSelected( object ) ) {

object.setFromInterfaceOwnerConcurrenceDate( value );

// add to map keeping details about the changed rows

// old itr value would anyway get replaced with this new one

mapChangedIntTableRows_uniqueIdToIntTableRow.put( object.getUniqueId(), object );

InterfaceTableDataModel.get().refreshDisplays();

}

else {

Window.alert( "Please select the row first to edit this field!!" );

((DatePickerCell) fromIntOwnConcDateColumn.getCell() ).clearViewData( InterfaceTableDataModel.KEY_PROVIDER.getKey( object ) );

//dataGrid.redraw();

dataGrid.redrawRow( index );

//selectionModel.setSelected( object, true );

//selectionModel.setSelected( object, false );

}

}

});

Thanks,
Ved
