当您键入电子邮件，旧密码，新密码并重新为您的配置文件修改新密码时，我有一些基本形式。我试图达到的目的是在通行证错误时显示反馈信息。一段代码如下所示：添加了反馈面板，但未显示所有消息
public class EditProfileForm extends Form<Void>
{
private static final long serialVersionUID = 1L;
// El-cheapo model for form
private final ValueMap properties = new ValueMap();
private ModalWindow modalWindow;
@SpringBean
UserManager userManager;
@SpringBean
Validator validator;
private User user;
private static final String EMAIL = "mp-email";
private static final String OLD_PASS = "mp-oldpass";
private static final String NEW_PASS = "mp-newpass";
private static final String NEW_PASS_REPEAT = "mp-newpassrepeat";
private static final String ERROR_WRONG_PASS = "Wrong pass";
private static final String ERROR_PASS_DIFF = "Pass diff";
private static final String ERROR_EMAIL_INVALID = "Wrong email";
private static final String ERROR_EMAIL_EXISTS = "Email used";
public EditProfileForm(String id, final ModalWindow modalWindow,final User u)
{
super(id);
this.user = u;
this.modalWindow = modalWindow;
add(new TextField<String>(EMAIL, new PropertyModel<String>(properties, EMAIL)).setRequired(true).setOutputMarkupId(true));
add(new PasswordTextField(OLD_PASS, new PropertyModel<String>(properties, OLD_PASS)).setOutputMarkupId(true));
add(new PasswordTextField(NEW_PASS, new PropertyModel<String>(properties, NEW_PASS)).setOutputMarkupId(true));
add(new PasswordTextField(NEW_PASS_REPEAT, new PropertyModel<String>(properties, NEW_PASS_REPEAT)).setOutputMarkupId(true));
final FeedbackPanel feedbackPanel = new FeedbackPanel("feedback");
feedbackPanel.setOutputMarkupId(true);
//feedbackPanel.setMaxMessages(5);
add(feedbackPanel);
AjaxSubmitLink closeBtn = new AjaxCloseCancelBtn("close-x", this);
AjaxSubmitLink cancelBtn = new AjaxCloseCancelBtn("cancel", this);
add(new AjaxSubmitLink("save", this)
{
private static final long serialVersionUID = 1L;
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form)
{
if (!user.getCryptedPassword().equals(CypherUtil.encodeMd5(getOldPassword())))
{
error(ERROR_WRONG_PASS);
}
else if (!getNewPassword().equals(getNewPasswordRepeat()))
{
error(ERROR_PASS_DIFF);
}
else if (!validator.validateEmailFormat(getEmail()))
{
error(ERROR_EMAIL_INVALID);
}
else if (validator.emailExists(getEmail()))
{
error(ERROR_EMAIL_EXISTS);
} else
{
//save user data
}
}
@Override
protected void onError(AjaxRequestTarget target, Form<?> form)
{
target.add(feedbackPanel);
}
});
add(closeBtn);
add(cancelBtn);
}
/**
* @return
*/
private String getEmail()
{
return properties.getString(EMAIL);
}
/**
* @return
*/
private String getOldPassword()
{
return properties.getString(OLD_PASS);
}
/**
* @return
*/
private String getNewPassword()
{
return properties.getString(NEW_PASS);
}
/**
* @return
*/
private String getNewPasswordRepeat()
{
return properties.getString(NEW_PASS_REPEAT);
}
}
现在，当我将这些表单留空时，我收到了很好的反馈信息，即有必要的字段。同时，当我输入错误的传球，电子邮件或者其他我什么都没有，我的服务器日志离开味精这样的：
WARNING: Component-targetted feedback message was left unrendered.
This could be because you are missing a FeedbackPanel on the page.
Message: [FeedbackMessage message = "Wrong pass", reporter = save, level = ERROR]
形式是网页是一个弹出窗口内：
public class ProfilePopup extends WebPage
{
private static final long serialVersionUID = 2929269801026361184L;
public ProfilePopup(final ModalWindow modal, final User user)
{
add(new EditProfileForm("profileModifyForm", modal, user).setOutputMarkupId(true));
}
}
和HTML，将反馈的形式外也没有帮助：
