Hi,

I'm using JSF 2.2.12 (latest version) and for some reason both tags below don't work:

<h:commandLink value="Cancel" action="#{bean.cancel}" immediate="true">
    <f:resetValues render=":form" />
</h:commandLink >

<h:commandLink value="Edit">
    <f:ajax render="@form" resetValues="true" />
    <f:setPropertyActionListener value="#{item}" target="#{bean.product}" />
</h:commandLink>

I'm using correct namespaces on page (http://xmlns.jcp.org/jsf/core and http://xmlns.jcp.org/jsf/html). Eclipse doesn't recognize tag f:resetValues, its code-completion doesn't work.

So far the only way I could clean up my form was programmatically using this method:

public void clean(UIComponent component) {
    if (component instanceof EditableValueHolder) {
        EditableValueHolder evh = (EditableValueHolder) component;
        evh.resetValue();
    }
    if (component.getChildCount()>0){
        for (UIComponent child : component.getChildren()) {
            this.clean(child);
        }
    }
}

Could you help me to understand what's happening?

Thanks!

I devised a sample category with subcategory module in jsf by eclipse. I made an adding category module without any issue but I couldn't make an adding subcategory under related category . Here the code below.

Suncategory .xhtml

<h:form>

<p:panelGrid columns="2">

    <h:outputLabel value="Category Name></h:outputLabel>

    <p:selectOneMenu value="#{subCategoryMB.categoryName}">
        <f:selectItem itemLabel="Select Category" itemValue=""></f:selectItem>
        <f:selectItems value="#{subCategoryMB.categorylist}" />
    </p:selectOneMenu>

    <h:outputLabel value="Category Name"></h:outputLabel>
    <p:inputText value="#{subCategoryMB.subcategory.subName}"></p:inputText>

    <h:outputLabel value="Category Description"></h:outputLabel>
    <p:inputText value="#{subCategoryMB.subcategory.subNameDes}"></p:inputText>

    <h:commandButton value="Add Subcategory" action="#{subCategoryMB.addSubCategory()}"></h:commandButton>


</p:panelGrid>

/h:form
</h:body

Category Dao

public List getAllcategoriesbyName(String name) {
// TODO Auto-generated method stub
Session session = HibernateUtil.getSessionFactory().openSession();

try {

    List<Category> liste = session.createQuery("from Category C where name='"+name+"'").list();
    return liste;


} catch (Exception e) {
    e.printStackTrace();

}finally {

    session.close();

}
return null;

}

public List getAllcategoriesSelectItemName() {
// TODO Auto-generated method stub
Session session = HibernateUtil.getSessionFactory().openSession();

    try {

        List<Category> liste = session.createQuery("Select C.name from Category C").list();

        return liste;


    } catch (Exception e) {
        e.printStackTrace();

    }finally {

        session.close();

    }
    return null;
}

SubCategoryMB

public class SubCategoryMB {

SubCategory subcategory = new SubCategory();

private String categoryName;
private List categorylist;
private List subCategoryList;
private Category category= new Category();

public SubCategoryMB() {
// TODO Auto-generated constructor stub
}

public SubCategory getSubcategory() {
return subcategory;
}

public void setSubcategory(SubCategory subcategory) {
this.subcategory = subcategory;
}

public List getCategorylist() {
CategoryDAO cDao = new CategoryDAO();
this.categorylist= cDao.getAllcategoriesSelectItemName();
return categorylist;
}

public void setCategorylist(List categorylist) {
this.categorylist = categorylist;
}

public String getCategoryName() {
return categoryName;
}

public void setCategoryName(String categoryName) {
this.categoryName = categoryName;
}

public Category getCategory() {
return category;
}

public void setCategory(Category category) {
this.category = category;
}

public List getSubCategoryList() {
SubCategoryDAO subDao = new SubCategoryDAO();
this.subCategoryList= subDao.getAllSubcategories();
return subCategoryList;
}

public void addSubCategory(){

       // ISSUE
            categorylistbySubCategory= new CategoryDAO().getAllcategoriesbyName(categoryName);
    category.setId(categorylistbySubCategory.get(0).getId());
    subcategory.setCategory(category);
    subcategory.setSubName(subcategory.getSubName());
    subcategory.setSubNameDes(subcategory.getSubNameDes());
    new SubCategoryDAO().addSubCategory(subcategory);

}
}

There is a problem about addSubCategory(). I can't add subcategory to its category.

your jsf22-cdi-viewscoped example is not one because you use ManagedBean instead of CDI Bean (@nAmed). CDI ViewScoped is managed by javax.faces.view.ViewScoped instead of javax.faces.bean.ViewScoped.
