До saveAction даже не доходит, поэтому выкладывать думаю смысла нет.

Уже пол часа гуглю, схожие проблемы вроде и есть на стековерфлоу, но приведенные там решения не помогают.

JSF: selectManyCheckbox does not work
Остался один небольшой момент, который я никак не догоняю.
Вот есть чекбоксы:

Код: xml
1.
2.
3.
4.
5.
6.
7.
8.
9.
10.
                                <p:selectManyCheckbox value="#{productView.selectedProduct.categories}">
                                    <f:selectItems
                                            value="#{productView.availableCategories}"
                                            var="category"
                                            itemLabel="#{category.name}"
                                            itemValue="#{category.id}"
                                    />
                                    <f:converter converterId="categoryConverter"/>
                                    <f:attribute name="collectionType" value="java.util.LinkedHashSet"/>
                                </p:selectManyCheckbox>




При сохранении валидатор ругается "form:j_idt87: Validation Error: Value is not valid"
Он пытается сравнить значение category.id с инстансом Category потому что.

Category.java
Код: java
1.
2.
3.
4.
5.
6.
    public boolean equals(Object object) {
        if (!(object instanceof Category))
            return false;

        return this.id.equals(((Category) object).getId());
    }



JSF передает сюда для валидации не инстанс Category, а его id, собстна поэтому он возвращает false и не дает сохранить форму.

Если захардкодить (для теста) return true; то все ок, форма сохраняется, в БД записывается.
Но мне тогда, получается, нужно будет костыль приделать типа

Код: java
1.
2.
3.
4.
5.
6.
7.
8.
9.
10.
    public boolean equals(Object object) {

        if (object instanceof Number && object.equals(this.getId()))
            return true;

        if (!(object instanceof Category))
            return false;

        return this.id.equals(((Category) object).getId());
    }



С таким методом все ок, работает. Но как-от он мне не нравится. Может я что-то упустил ранее.

    public String getAsString(FacesContext context, UIComponent component, Object entity) {
        synchronized (entities) {
            if (!entities.containsKey(entity)) {
                String uuid = UUID.randomUUID().toString();
                entities.put(entity, uuid);
                return uuid;

    }


    public Object getAsObject(FacesContext context, UIComponent component, String uuid) {
        for (Map.Entry<Object, String> entry : entities.entrySet()) {
            if (entry.getValue().equals(uuid)) {
                return entry.getKey();
            }
        }
        return null;
    }

}



Работает на первый взгляд нормально.
Я так понял его жизненный цикл будет зависеть от управляемого бина, в котором он используется?
