Here is my solution that works for me:
public class GroupDataAlertDataGrid extends FlexTable {
private Button dismissButton;
private int row;
void addDataToFlexTable(LocationsInfoDTO locationsInfoDTO)
{
for(final Info info : locationsInfoDTO.getInfos()){
dismissButton = new Button("Dismiss");
this.setWidget(row, 1, new Label(info.getLocationCode()));
this.setWidget(row, 2, new Label(info.getClientName()));
this.setWidget(row, 3, dismissButton);
dismissButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
Cell cell = getCellForEvent(event);
int receiverRowIndex = cell.getRowIndex();
//make the row invisible
getRowFormatter().setVisible(receiverRowIndex, false);
GwtAlertServicesDelegate.getService().removeLocationInfoFromSession(info,
new
AsyncCallback<LocationsInfoDTO>() {
@Override
public void
onFailure(Throwable arg0) {}
@Override
public void
onSuccess(LocationsInfoDTO arg0) {}
}
);
}
});
row++;
}
}
}
