h:inputSecret redisplay =“false”required =“false”>

我使用seam 2.2.0.GA. 我的密码/确认字段有redisplay =“false”,因此当前密码不在html中。 validateEquality位于确认字段中。

我想要以下行为:当我创建一个新实体时,应该都需要密码/确认字段。当我编辑实体时,不应该要求这两个字段,但在任何情况下都应该检查相等性。为此,我有h:inputSecret required =“#{required}”并计算参数“required”。

有两个问题:

1)s:validateEquality也具有“required”属性,但它看起来有些错误:如果我硬编码为true或false,它按预期工作,但如果我使用required =“#{required}”并且在对话期间param更改后,验证程序的行为仍然就像param没有更改一样。

2)s:如果确认字段为空,则validateEquality required =“false”不检查相等性。

问题#1:

以下代码会转换您的&#34; required&#34;现场静态,我相信:

<ui:param name="required" value="#{sandboxBean.required}"/>

问题#2:

http://seamframework.org/Community/CustomValidatorUsingTwoFields

使用标有相应注释的自定义验证器,然后可以使用自定义验证器调用。

@Validator
public class PasswordValidator implements javax.faces.validator.Validator, Serializable{
...
throw new ValidatorException(new FacesMessage("Passwords do not match."));

public class PasswordConverter
    implements Converter
{
    public static String DONT = "__dontchange__";

    public Object getAsObject(FacesContext context, UIComponent component, String value)
    {
        if (DONT.equals(value) && component instanceof UIOutput) {
            return ((UIOutput)component).getValue();
        } else {
            return value;
        }
    }

    public String getAsString(FacesContext context, UIComponent component, Object value)
    {
        if (value instanceof String && component instanceof UIOutput && ((String)value).length() > 0) {
            return DONT;
        } else if (value == null) {
                return null;
        } else {
            return value.toString();
        }
    }
