Problem with sizing of components

Hi,

I've got a problem with not displayed components when using a form. I've created a custom component with the gui builder, containing the openlayers addon.
Now I want to access the fields in the component with the Formbinder addon.
If I display the custom Component with out the formBinder everything looks fine - It takes all the place which is there, and the map takes all the place which the tow other components do not need.
If I put it in the form binder its not displaying the custom component.
What do I do wrong here?

The custom component:

package com.example.vaadin_test;

import org.vaadin.vol.OpenLayersMap;
import org.vaadin.vol.OpenStreetMapLayer;

import com.vaadin.annotations.AutoGenerated;
import com.vaadin.ui.CustomComponent;
import com.vaadin.ui.PopupDateField;
import com.vaadin.ui.TextField;
import com.vaadin.ui.VerticalLayout;

public class CustomForm extends CustomComponent
{

    @AutoGenerated
    private VerticalLayout mainLayout;
    @AutoGenerated
    private TextField textField;
    @AutoGenerated
    private PopupDateField dateField;
    @AutoGenerated
    private OpenLayersMap positionField;

    /**
     * The constructor should first build the main layout, set the composition
     * root and then do any custom initialization.
     * 
     * The constructor will not be automatically regenerated by the visual
     * editor.
     */
    public CustomForm()
    {
	buildMainLayout();
	setCompositionRoot(mainLayout);

	// TODO add user code here
	positionField.addLayer(new OpenStreetMapLayer());

    }

    @AutoGenerated
    private VerticalLayout buildMainLayout()
    {
	// common part: create layout
	mainLayout = new VerticalLayout();
	mainLayout.setImmediate(false);
	mainLayout.setWidth("100%");
	mainLayout.setHeight("100%");
	mainLayout.setMargin(true);
	mainLayout.setSpacing(true);

	// top-level component properties
	setWidth("100.0%");
	setHeight("100.0%");

	// positionField
	positionField = new OpenLayersMap();
	positionField.setImmediate(false);
	positionField.setWidth("100.0%");
	positionField.setHeight("100.0%");
	mainLayout.addComponent(positionField);
	mainLayout.setExpandRatio(positionField, 1.0f);

	// dateField
	dateField = new PopupDateField();
	dateField.setImmediate(false);
	dateField.setWidth("-1px");
	dateField.setHeight("-1px");
	dateField.setInvalidAllowed(false);
	mainLayout.addComponent(dateField);

	// textField
	textField = new TextField();
	textField.setImmediate(false);
	textField.setWidth("-1px");
	textField.setHeight("-1px");
	textField.setSecret(false);
	mainLayout.addComponent(textField);

	return mainLayout;
    }

}

The application with out the formbinder - works, but no binding

package com.example.vaadin_test;

import org.vaadin.addon.formbinder.ViewBoundForm;

import com.vaadin.Application;
import com.vaadin.data.util.BeanItem;
import com.vaadin.ui.Button;
import com.vaadin.ui.VerticalLayout;
import com.vaadin.ui.Button.ClickEvent;
import com.vaadin.ui.Window;

public class Vaadin_testApplication extends Application
{

    @Override
    public void init()
    {
	final Window mainWindow = new Window("Vaadin_test Application");
	Button button = new Button("Show pojo state");
	button.addListener(new Button.ClickListener()
	{

	    public void buttonClick(ClickEvent event)
	    {
		mainWindow.showNotification("Pojo state: " + myPojo);

	    }
	});
	VerticalLayout layout = new VerticalLayout();

	layout.addComponent(customForm);
	layout.addComponent(button);
	layout.setExpandRatio(customForm, 1.00f);
	layout.setExpandRatio(button, 0.00f);
	layout.setHeight("100%");
	mainWindow.setContent(layout);
	setMainWindow(mainWindow);
    }

}

The application with the formBinder, does not display the content of the customComponent

package com.example.vaadin_test;

import org.vaadin.addon.formbinder.ViewBoundForm;

import com.vaadin.Application;
import com.vaadin.data.util.BeanItem;
import com.vaadin.ui.Button;
import com.vaadin.ui.Button.ClickEvent;
import com.vaadin.ui.VerticalLayout;
import com.vaadin.ui.Window;

public class Vaadin_testApplication extends Application
{

    @Override
    public void init()
    {
	final Window mainWindow = new Window("Vaadin_test Application");
	final MyPojo myPojo = new MyPojo();
	CustomForm customForm = new CustomForm();
	myPojo.setPosition("Bla");
	ViewBoundForm form = new ViewBoundForm(customForm);
	form.setSizeFull();
	form.setCaption("MyCustomForm");
	form.setItemDataSource(new BeanItem<MyPojo>(myPojo));

	Button button = new Button("Show pojo state");
	button.addListener(new Button.ClickListener()
	{

	    public void buttonClick(ClickEvent event)
	    {
		mainWindow.showNotification("Pojo state: " + myPojo);

	    }
	});
	VerticalLayout layout = new VerticalLayout();

	layout.addComponent(form);
	layout.addComponent(button);
	layout.setExpandRatio(form, 1.00f);
	layout.setExpandRatio(button, 0.00f);
	layout.setHeight("100%");
	mainWindow.setContent(layout);
	setMainWindow(mainWindow);
    }

}
