ManageBean method don't works anymore because of FacesValidator?
I was having some problem with password validation, which @BalusC help me out, here. But aft开发者_开发百科er I insert the validation code in my form, when I call the controller method, nothing happens. Here goes my JSF page: Register.xhtml
<!DOCTYPE html>
<html lang="pt-br"

<h:form id="form">
<h:panelGrid columns="3" >
<h:outputLabel for="name" value="Nome:" />
<h:inputText id="name" value="#{register.person.name}" >
<f:ajax event="blur" listener="#{register.validateName}" render="m_name" />
</h:inputText>
<rich:message id="m_name" for="name" ajaxRendered="false"/>
// some fields ..
<h:outputLabel for="password" value="Password" />
<h:inputSecret id="password" value="#{register.user.password}">
<f:validator validatorId="confirmPasswordValidator" />
<f:attribute name="confirm" value="#{confirmPassword.submittedValue}" />
<f:ajax event="blur" execute="password confirm" render="m_password" />
</h:inputSecret>
<rich:message id="m_password" for="password" />
<h:outputLabel for="confirm" value="Senha (novamente):" />
<h:inputSecret id="confirm" binding="#{confirmPassword}" >
<f:ajax event="blur" execute="password confirm" render="m_password m_confirm" />
</h:inputSecret>
<rich:message id="m_confirm" for="confirm" />
<h:commandButton value="Register" action="#{register.registerPerson}" >
<f:ajax execute="@form" render="@form" />
</h:commandButton>
<h:outputText value="#{register.recordStatus}" id="out" />
<a4j:status>
<f:facet name="start">
<h:graphicImage name="loader.gif" library="image"/>
</f:facet>
</a4j:status>
</h:panelGrid>
</h:form>
</h:body>
</html>
So when I fill the form and try to register, nothing happens, not even any exception it's lauched.
The passwod validator (thanks BalusC mate):
@FacesValidator("confirmPasswordValidator")
public class ConfirmPasswordValidator implements Validator {
@Override
public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
String password = (String) value;
String confirm = (String) component.getAttributes().get("confirm");
if (password == null || confirm == null) {
return; // Just ignore and let required="true" do its job.
}
if (!password.equals(confirm)) {
throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "password not equal"));
}else{
throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_INFO, null, "ok"));
}
}
}
I think this problem is very weird, I really don't know what's happening here. Thanks guys.
You threw a ValidatorException on a succesful match.
if (!password.equals(confirm)) {
throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "password not equal"));
} else {
throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_INFO, null, "ok"));
}
This causes JSF to block the form submit. The severity doesn't matter. A validator exception is a validator exception. It indicates a vaildation failure.
Rather use FacesContext#addMessage() instead.
if (!password.equals(confirm)) {
throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "password not equal"));
} else {
context.addMessage(component.getClientId(), new FacesMessage(FacesMessage.SEVERITY_INFO, null, "ok"));
}
加载中,请稍侯......
