javax.la validation.ValidationException: HV000028: exception Inattendue au cours de isValid appel tout en utilisant un f:convertNumber à l'intérieur d'un p/h:dataTable

Je suis en train d'utiliser un <f:convertNumber> à l'intérieur d'un <p:dataTable> comme suit.

<p:column headerText="Text">
    <p:cellEditor>
        <f:facet name="output">
            <h:outputText value="#{country.countryCode}"/>
        </f:facet>
        <f:facet name="input">
            <p:inputText value="#{country.countryCode}" required="true">
                <f:validateLength minimum="1" maximum="45"/>
                <f:convertNumber integerOnly="true" type="number"/>
            </p:inputText>
        </f:facet>
    </p:cellEditor>
</p:column>

Où country.countryCode est un type de Chaîne de propriété dans les modèles de données associés.

Je suis l'exception suivante:

Pourquoi ne pas <f:convertNumber> de travail à l'intérieur d'un <p:dataTable>? Cela peut-il être au travail?

Je n'ai jamais eu de problèmes à l'aide de <f:convertNumber> à l'intérieur d'un <p:dataTable> et une simple aire de jeux exemple semble fonctionner très bien avec moi

Votre erreur est provoquée par la présente:
```
Caused by: java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.CharSequence
```
Essayer de localiser l'endroit où vous êtes en essayant d'analyser un long. Peut-être son long dans la base de données et que vous essayez de le mettre dans une Chaîne de caractères?
- Je ne suis pas d'analyser countryCode à Long n'importe où. Le country_code colonne dans la base de données est de type VARCHAR(45) qui est connecté par un correspondant de la propriété de type Chaîne de caractères dans la JPA. L'exception se produit uniquement lorsque <f:convertNumber> est utilisé à l'intérieur d'un <p:dataTable> ou <h:dataTable>. Il fonctionne de manière intuitive autrement.
- Je ne sais pas la raison derrière l'exception, mais je pense que <f:convertNumber> ne doit pas être utilisé de manière intuitive (c'est un convertisseur), quand il y a une colonne de type VARCHAR(size) représentant une propriété de type Chaîne de caractères dans le modèle (alors que je suis incertain quant à savoir si ou de ne pas <f:convertNumber> peut être utilisé dans cette situation). J'utilise simplement <f:validateRegex pattern="[0-9]*" /> à suffire à la condition de permettre uniquement des chiffres dans le <p:inputText>. À l'aide de la regex, les associés <p:inputText> peut aussi être laissé vide afin de déléguer la nécessaire validation de required="true".

Par la convention (conception) les validateurs courir après les convertisseurs car ils doivent toujours valider le "busininess' objets, et non pas la valeur textuelle de l'envoyer par le client.

De sorte que le (explicite) f:convertNumber est exécutée en premier, la conversion de la valeur qui est affiché par le client à un java.lang.Long dans ce cas. Suivant la f:validateLength est exécuté et que le validateur s'attend à un java.lang.String, puisque c'est la la définition de ce f:validateLength, de valider la longueur d'un chaîne (pas un nombre). Mais l'Entier de l'objet peut être "traité" comme une chaîne de caractères, mais vous obtiendrez la valeur de hachage qui a sa longueur validé, PAS le contenu. Il ne va pas planter mais ne fonctionne pas comme vous l'attendez.

De manière efficace que vous utilisez une mauvaise combinaison de programme de validation et de convertisseur. D'autant plus que vous semblez être le stockage de l'indicatif du pays comme un varChar de nouveau, mais de les convertir en un nombre (Long) en premier. Puisque vous semblez aussi avoir des contraintes sur les entités, JSF automatiquement les feux de la validation de ce champ et dans cette étape, il essaie de faire des validations sur ces. Dans cette étape, le classCast se produit.

Il n'est pas nécessaire de convertir un nombre premier, mais le f:validateLength en combinaison avec un f:validateRegex pattern="[0-9]*" devrait être suffisant comme @Minuscules déjà dit. Heck, si vous avez des contraintes sur les entités, il n'est pas nécessaire pour les validateurs dans l'INTERFACE utilisateur à tous.
