DynamicForm and RestDataSource

Hi, I have litle problem with integration of DynamicForm to server side.
I try to implement my own implementation of RestDataSource, but when I submit my form, empty message(without data) is sent to server. Can I ask how to bind DynamicForm to datasource(generate full DSMessage)?

My implementation of RestDataSource :

public class ContactDS extends RestDataSource {

	public ContactDS() {
setID("MessageDS");
DataSourceTextField idField = new DataSourceTextField("contactId");
idField.setPrimaryKey(true);
idField.setCanEdit(false);
DataSourceTextField firstNameField = new DataSourceTextField("name");
DataSourceTextField lastNameField = new DataSourceTextField("surname");
DataSourceTextField emailField = new DataSourceTextField("emailAdress"); DataSourceTextField telephoneNumberField = new DataSourceTextField("telephoneNumber");
setFields(idField,firstNameField, lastNameField, emailField, telephoneNumberField);
        
        OperationBinding fetch = new OperationBinding();
        fetch.setOperationType(DSOperationType.FETCH);
        fetch.setDataProtocol(DSProtocol.POSTMESSAGE);
        OperationBinding add = new OperationBinding();
        add.setOperationType(DSOperationType.ADD);
        add.setDataProtocol(DSProtocol.POSTMESSAGE);
        add.setDataFormat(DSDataFormat.XML);
        OperationBinding update = new OperationBinding();
        update.setOperationType(DSOperationType.UPDATE);
        update.setDataProtocol(DSProtocol.POSTMESSAGE);
        OperationBinding remove = new OperationBinding();
        remove.setOperationType(DSOperationType.REMOVE);
        remove.setDataProtocol(DSProtocol.POSTMESSAGE);
        setOperationBindings(add, fetch, update, remove);
        this.setDataFormat(DSDataFormat.XML);   
        setFetchDataURL("http://localhost:8888/rest/contacts/read");
        setAddDataURL("http://localhost:8888/rest/contacts/add");
        setUpdateDataURL("http://localhost:8888/rest/contacts/update");
        setRemoveDataURL("http://localhost:8888/rest/contacts/remove");
	}
}

My UI:

public class HellerDynamicFormPane extends VLayout{

	TextItem name;
	TextItem surname;
	TextItem telephoneNumber;
	TextItem emailAdress;
	DynamicForm form;
	ContactDS contactDS;
	
	public HellerDynamicFormPane() {
		super();
		this.initLayout();
		this.setWidth("50%");
		this.setHeight("50%");
	}
	
	public void initLayout() {
		//this.setAutoHeight();
		HeaderItem headerItem = new HeaderItem();
		headerItem.setDefaultValue("New Contact form");
		
		form = new DynamicForm();
		form.setWidth(400);
		
		this.name = new TextItem();
		name.setName("name");
		name.setTitle("Username");
	
		this.surname = new TextItem();
		surname.setName("surname");
		surname.setTitle("Surname");
		
		this.telephoneNumber = new TextItem();
		telephoneNumber.setName("telephoneNumber");
		telephoneNumber.setTitle("Telephone Number");
		
		this.emailAdress = new TextItem();
		emailAdress.setName("emailAdress");
		emailAdress.setTitle("Email Adress");
		
		final ButtonItem buttonItem = new ButtonItem();  
		buttonItem.setTitle("Ok"); 

		buttonItem.addClickHandler(new ClickHandler() {  
		    
			@Override
public void onClick(com.smartgwt.client.widgets.form.fields.events.ClickEvent event) {
			form.saveData();
			}  
		});  
		
		form.setDataSource(new ContactDS());
		form.setFields(headerItem, name, surname, telephoneNumber,     emailAdress, buttonItem);
		this.addMember(form);
		//this.draw();
	}
}

Thanks for help.

DSProtocol.POSTMESSAGE means that the content is posted as content, not parameters, like this:

{ "dataSource":"AT", "operationType":"add", "componentId":"isc_ValuesManager_5", "data":{ "type":"CONTAINER", "position":0, "parentId":null, "title":"test", "enumMap":{ }, "attributes":[ ] }, "oldValues":{ } }

Use firebug and/or developer console to doublecheck what's going on when the request is fired. If you expect the parameters to be directly in the request, use DSProtocol.POSTPARAMS instead.
