Problem With Vaadin + Eclipse + Visual Editor Update

I created a Vaadin Project, then wanted to create a Custom composite and display that as my main window (so i could take advantage of the Visual UI editor). Working with Tomcat Apache Server and the Visual Editor has been a pain! Nothing updates even when i start, stop or restart the server. My mainWindow application will display some Vaadin components and not others. Here is an example i have of my main window code

package com.example.dugsi_manager;

import com.vaadin.Application;
import com.vaadin.ui.*;
import com.example.dugsi_manager.ui.component.*;
public class Dugsi_managerApplication extends Application {
	

	
	@Override
	public void init() {
		Window mainWindow = new Window("Dugsi_manager Application");
		 //Header header = new Header();
		 //header.setSizeFull();
		DugsiHome dugsiHome = new DugsiHome();	 // [b]
[color=#c22525]
 HERE IS THE COMPOSITE INSTANCE I CREATED IN ECLIPSE
[/color]
[/b]
		dugsiHome.setSizeFull();
		mainWindow.getContent().setSizeFull();
		 mainWindow.addComponent(dugsiHome);
		 setMainWindow(mainWindow);
		 setTheme("dugsi_managertheme");



	}

}

Is this a bug or a problem with others using these same tool for making vaadin applications. My application even if i shut off my machine wont update with newly components added to the composite (DugsiHome)?
