Problem with refreshing a Flextable after changes

Hello everybody,

I build my own GWT App which shows mainly a FlexTable (campaignTable) with campaign objects in it. The campaign objects are saved in an array in my main class. To change the data of the campaign, I have a button (editButton) which opens with its clickhandler a popup. In that popup I can change the data of the corresponding object. Has anyone an idea on how I get the changed data in my main flexTable?

Thank you!

The corresponding source code of the main class is:

public class MyCampaign implements EntryPoint {

private VerticalPanel mainPanel = new VerticalPanel(); 

private FlexTable campaignTable = new FlexTable(); 

private HorizontalPanel addPanel = new HorizontalPanel(); 

private TextBox campaignName = new TextBox(); 

private TextBox spendenziel = new TextBox(); 

private TextBox spendenbetrag = new TextBox(); 

private TextBox spenderName = new TextBox(); 

private TextBox iban = new TextBox(); 

private TextBox bankName = new TextBox();

private Button saveButton = new Button("Speichern");

private Button cancelButton = new Button("Abbrechen");

private FlexTable addTable = new FlexTable(); 

private FlowPanel main = new FlowPanel(); 

private FlowPanel header = new FlowPanel(); 

private DisclosurePanel disPanel = new DisclosurePanel(); 

private Campaign campaign; 

private ArrayList<Campaign> campaignArray = new ArrayList<Campaign>();

public void onModuleLoad() {

FlexCellFormatter cellFormatter = campaignTable.getFlexCellFormatter();

campaignTable.addStyleName("campaignTable");

    campaignTable.setCellSpacing(5);

    campaignTable.setCellPadding(3);

campaignTable.getRowFormatter().addStyleName(0, "campaignListHeader");

campaignTable.setText(0, 0, "Name"); 

campaignTable.setText(0, 1, "Spendenziel"); 

campaignTable.setText(0, 2, "bisher gespendet"); 

campaignTable.setText(0, 3, ""); 

campaignTable.setText(0, 4, ""); 

campaignTable.setText(0, 5, ""); 

campaignTable.setText(0, 6, "");
