Hi, I'm trying to "compose" the widget, but I get the same mistake.I
simplified the code of 2 modules that I consider:
---------
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.VerticalPanel;
import com.google.gwt.user.client.ui.Composite;
public class MenuHome extends Composite {
public void Composite() {
VerticalPanel vPanel = new VerticalPanel();
vPanel.setTitle("GOOD!");
vPanel.setWidth("100%");
vPanel.setHorizontalAlignment(VerticalPanel.ALIGN_CENTER);
initWidget(vPanel);
RootPanel.get().add(vPanel);}
}
-----------------
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.Window;
public class Home implements EntryPoint {
private MenuHome menuhome;
public void onModuleLoad() {
Window.setTitle("Title");
menuhome = new MenuHome();
RootPanel.get().add(menuhome);
}
}
------------------------------
MenuHome.gwt.xml
<module>
<inherits name='com.google.gwt.user.User'/>
<entry-point class='com.gwt.client.MenuHome'/>
<stylesheet src='MenuHome.css' />
</module>
---------------------------------
Home.gwt.xml
<module>
<inherits name='com.google.gwt.user.User'/>
<inherits name='com.google.gwt.user.theme.standard.Standard'/>
<entry-point class='com.gwt.client.Home'/>
<stylesheet src='Home.css' />
</module>
------------------------------------------
MenuHome.html
<html>
<head>
<meta http-equiv="content-type" content="text/html;
charset=UTF-8">
<title>MenuHome</title>
<script type="text/javascript" language="javascript"
src="com.gwt.MenuHome.nocache.js"></script>
</head>
<body>
<iframe src="javascript:''" id="__gwt_historyFrame" tabIndex='-1'
style="position:absolute;width:0;height:0;border:0"></iframe>
</body>
</html>
---------------------------------
Home.html
<html>
<head>
<meta http-equiv="content-type" content="text/html;
charset=UTF-8">
<title>Home</title>
<script type="text/javascript" language="javascript"

</head>
<body>
<iframe src="javascript:''" id="__gwt_historyFrame" tabIndex='-1'
style="position:absolute;width:0;height:0;border:0"></iframe>
