Problem with refreshing a Flextable after changes

[Joyce]

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, "");

loadData();

// Disclosure Panel

The source code of the Edit Campaign class is the following:

Add a close handler to your edit campaign dialog box and once it closes
re-render the corresponding row.

Hi Jens,
how can I add a CloseHandler?
I thought that the class MyCampaign should implemts the CloseHandler for
the EditCampaign class.
My Problem is then: How do I get the changed Campaign data to the
MyCampaign class?
Do you have any ideas?
Thank you!
