java - validator 未触发

Question

我有这个组件:

<ice:form style="width: 45%;" partialSubmit="true" >
    <ice:inputText id="cc" required="true" partialSubmit="true" immediate="true"
        value="#{userAction.username}">
        <f:validator validatorId="passwordValidator" />
        <ice:message style="color: red;" id="ageError" for="cc" />
    </ice:inputText>
</ice:form>

我已经在 faces 配置中声明了 validator :

<validator>
    <validator-id>passwordValidator</validator-id>
    <validator-class>com.mydomain.seam_icefaces_test.action.PasswordValidator</validator-class>
</validator>

以及 validator java 类:

   package com.mydomain.seam_icefaces_test.action;

import javax.faces.component.UIComponent;
import javax.faces.component.UIInput;
import javax.faces.context.FacesContext;
import javax.faces.validator.Validator;
import javax.faces.validator.ValidatorException;

    import org.jboss.seam.faces.FacesMessages;

    public class PasswordValidator implements Validator {

        @Override
        public void validate(FacesContext arg0, UIComponent arg1, Object value)
                throws ValidatorException {
            String val = (String) value;

            if (val.length() == 0)
                ((UIInput) arg1).setValid(false);
            FacesMessages.instance().addToControlFromResourceBundle(arg1.getId(),
                    "invalid.password");

        }
    }

我不明白为什么它在失去焦点时不会触发......

你有什么想法吗？

谢谢。

JSF validator 在验证过程中被调用。当控制失去焦点时，它们不会被调用。请参阅lifecycle .
