Uncaught JavaScript exception [Script error.] in , line 0

Just letting you know that your code does not reproduce a problem. Something is wrong with your project, not the code.

I have changed it as you have suggested, unfortunately the warning persists.

Do not use RootLayoutPanel.get().add(mainLayout); with SmartGWT. Use mainLayout.draw() instead. Let us know if that helps.

Hello,

I am using SmartGWT 3.0, Firefox 10.0.2, Firefox Developer Plugin 1.0.10862. The very simple entrypoint class below causes a "Uncaught JavaScript exception [Script error.] in , line 0" warning when I run on development mode in Firefox. With Google Chrome or IE9 developer plugin, I do not get the warning.

I have no idea about how to trace the cause of the problem as the warning message is quite cryptic.

public class LoginTrial implements EntryPoint {

	  final LoginServiceAsync serviceProxy = (LoginServiceAsync) GWT.create(LoginService.class);
	  final ServiceDefTarget target = (ServiceDefTarget) serviceProxy;	
	  private VLayout mainLayout;	

	public void onModuleLoad() {

	Window.enableScrolling(false);
	Window.setMargin("100px");
	 
	// initialise the main layout container
	mainLayout = new VLayout();
	mainLayout.setWidth100();  
        mainLayout.setHeight100(); 
	   
	// Log in form
	final DynamicForm loginform = new DynamicForm();  
        loginform.setWidth(250); 
        loginform.setID("loginform");

        TextItem usernameItem = new TextItem();  
        usernameItem.setTitle("User Name");  
        usernameItem.setRequired(true);  
        usernameItem.setName("username");	
        
        PasswordItem passwordItem = new PasswordItem();  
        passwordItem.setTitle("Password");  
        passwordItem.setRequired(true);  
        passwordItem.setName("password");	
        
        loginform.setFields(new FormItem[] {usernameItem, passwordItem});  
        loginform.setPadding(10);
        loginform.setBorder("1px solid gray");
        
        // Log in Button
        IButton loginbutton = new IButton("Log in");  
        mainLayout.addMember(loginform);    
        mainLayout.addMember(loginbutton);

	// add the main layout container to GWT's root panel 
	RootLayoutPanel.get().add(mainLayout);  
	}
}
