从myfaces切换到mojarra后发生IndexOutOfBoundsException

我被迫从myfaces（2.1.7）切换到mojarra（2.1.7）。在此之后，我收到了这样一个例外情况。从myfaces切换到mojarra后发生IndexOutOfBoundsException

我正在提交表单，这给我验证错误。到目前为止这是正确的。我再次提交表单，这给我验证错误。到目前为止这是正确的。现在我再次提交表单，并得到IndexOutOfBoundsException。

我用google搜索了这个，但还没有找到任何线索呢。

stacktrace暗示您正在使用PrimeFaces。

此问题在PrimeFaces的旧版本中已知，实际上是PrimeFaces中的一个错误，而不是在Mojarra中。确保您使用的是PrimeFaces版本。到目前为止，当您使用PF2时为2.2.1，或者当您使用PF3时为3.2。

嗨BalusC，感谢您的quichk答复。我看到了这个问题，但我不认为它这一点。我使用PF3.2我缩小了它，当我使用''就像这样'' \t \t '我正在运行进入这个错误。删除禁用验证的东西_solves_它。我很困惑。 – user871611

昨天我遇到了同样的问题，并且不得不搜索很长一段时间解决这个问题。我希望人们在需要的时候找到这个页面，因为问题是由validateBean组件引起的。不需要删除标签，但在进入另一个转换之前，您需要刷新页面。一种方法是将“ajax ='false'”添加到提交表单的命令按钮中。希望这将有助于未来的人:) – devnomore

我有完全相同的问题，很容易重现。
你可以用下面的类重现：

验证：

@FacesValidator("testValidator") 
public class TestValidator implements Validator { 

    @Override 
    public void validate(FacesContext fc, UIComponent uic, Object o) throws ValidatorException { 
     if (!(o instanceof Integer)) { 
      throw new ValidatorException(new FacesMessage("validation message!")); 
     } 
    } 
}

FacesComponent：

@ListenerFor(systemEventClass = PreValidateEvent.class) 
@FacesComponent("testField") 
public class TestField extends UIComponentBase implements NamingContainer { 

@Override 
public String getFamily() { 
    return UINamingContainer.COMPONENT_FAMILY; 
} 

@Override 
public void processEvent(ComponentSystemEvent event) throws AbortProcessingException { 
    super.processEvent(event); 
    UIComponent findComponent = findComponent("input"); 
    if (findComponent instanceof UIInput) { 
     UIInput i = (UIInput) findComponent; 
     boolean notFound = true; 
     for (Validator v : i.getValidators()) { 
      if (v instanceof TestValidator) { 
       notFound = false; 
      } 
     } 
     if (notFound) { 
      i.addValidator(new TestValidator()); 
     } 
    } 
} 

}

自定义组件：

<?xml version='1.0' encoding='UTF-8' ?> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml" 
     xmlns:h="http://java.sun.com/jsf/html" 
     xmlns:cc="http://java.sun.com/jsf/composite"> 

    <!-- INTERFACE --> 
    <cc:interface componentType="testField"> 
    </cc:interface> 

    <!-- IMPLEMENTATION --> 
    <cc:implementation> 
     field: <h:inputText id="input" value="#{testController.inputText}" /> 
    </cc:implementation> 
</html>

ManagedBean：

@SessionScoped 
@Named("testController") 
public class TestController implements Serializable { 

private static final long serialVersionUID = 1L; 

private String inputText = ""; 

public TestController() { 
} 

public void actionListener(ActionEvent event) { 

} 

public String myAction() { 
    return ""; 
} 

public String getInputText() { 
    return inputText; 
} 

public void setInputText(String inputText) { 
    this.inputText = inputText; 
} 

}

的index.xhtml

<?xml version='1.0' encoding='UTF-8' ?> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml" 
     xmlns:t="http://java.sun.com/jsf/composite/test" 
     xmlns:f="http://java.sun.com/jsf/core" 
     xmlns:h="http://xmlns.jcp.org/jsf/html"> 
    <h:head> 
     <title>Jsf Problem</title> 
    </h:head> 
    <h:body> 
     <h:form>  
      <h:messages /> 
      <t:field /> 
      <h:commandButton value="Submit" action="#{testController.myAction()}" /> 
     </h:form> 
    </h:body> 
</html>

定制组件字段内的的inputText得到一个新的验证添加在的processEvent（）方法内PreValidateEvent。
如果提交按钮现在连续按下三次并出现验证错误，则抛出ArrayIndexOutOfBoundException异常。我试图调试，发现这个异常抛在了AttachedObjectListHolder＃restoreState（FacesContext，Object）里面，之后我的eclipse调试器变得疯狂了......

我觉得这是一个JSF Bug！

我想发表评论，但我'不许尚未... :(
