Here is my code:

{code} 
public void testLoginSucesso() throws IOException    {
  // Send an HTTP request for the initial page       
  JSFSession jsfSession = new JSFSession("/default.jsf?menuForm:transactionIDHidden=br.com.ymf.amplis.security.view.SEC_00001");              
  // A JSFClientSession emulates the browser and lets you test HTML       
  JSFClientSession client = jsfSession.getJSFClientSession();              
  System.out.print(client.getPageAsText());
  FrameWindow frame = ((HtmlPage) client.getContentPage()).getFrameByName("applicationMainFrame");
  HtmlPage paginaLogin = (HtmlPage) frame.getEnclosedPage();
  HtmlInput login = paginaLogin.getHtmlElementById("loginForm:userLoginInput");
 
  paginaLogin = (HtmlPage)login.setValueAttribute("AMPLIS"); 
 
  HtmlInput senha = paginaLogin.getHtmlElementById("loginForm:userPasswordInput");
 
  paginaLogin = (HtmlPage)senha.setValueAttribute("123456"); 
 
  HtmlImageInput botao = paginaLogin.getHtmlElementById("loginForm:loginButton");
 
  paginaLogin = (HtmlPage) botao.click();
    
  assertTrue(paginaLogin.asText().contains("Mensagens Corporativas"));
 }
{code}

 
 The problem ocurrs in:
 paginaLogin = (HtmlPage) botao.click();
 
 But in the same class I also have the test:
 
 

{code} 
public void testSemSenha() throws IOException  {
  // Send an HTTP request for the initial page       
  JSFSession jsfSession = new JSFSession("/default.jsf?menuForm:transactionIDHidden=br.com.ymf.amplis.security.view.SEC_00001");              
  // A JSFClientSession emulates the browser and lets you test HTML       
  JSFClientSession client = jsfSession.getJSFClientSession();              
  System.out.print(client.getPageAsText());
  FrameWindow frame = ((HtmlPage) client.getContentPage()).getFrameByName("applicationMainFrame");
  HtmlPage paginaLogin = (HtmlPage) frame.getEnclosedPage();
  HtmlInput login = paginaLogin.getHtmlElementById("loginForm:userLoginInput");
 
  paginaLogin = (HtmlPage)login.setValueAttribute("AMPLIS"); 
 
  HtmlImageInput botao = paginaLogin.getHtmlElementById("loginForm:loginButton");
 
  paginaLogin = (HtmlPage) botao.click();
    
  assertEquals("Informe o Usuário e a Senha", paginaLogin.getHtmlElementById("detailMessageListBoxId").getTextContent());
  
 }
{code}

And this test works fine, the difference is that the first test makes a sucessfull login 
and the second one informs a missing password.
 
Other important point is that if I migrate to JSFUnit 1.2 and HTMLUnit 2.7 then 
 both tests works correctly. 

Anyone knows the reason?

I suspect that when you got a successful login your HttpSession was wiped out.  This happens with some security frameworks.  When you clean the HttpSession with JSFUnit then everything JSFUnit needs is protected.  But if you get the HttpSession outside of JSFUnit and you invalidate the session then JSFUnit won't work properly.

The way to fix this is to use an AuthenticationStrategy that logs you in using plain HtmlUnit before proceeding with the rest of the test.  See this page for details.  Also note the section at the end about logging out.  That alludes to the problem I was talking about with the HttpSession that sometimes happens on login.
