Problemas com Spring+JSF

Front-end
#1

Pessou estou sofrendo para usar Spring+JSF.

Estou com problemas quanto tendo saber qual row eu selecionei para poder excluir (categoryM.delete) em um HTMLDataTable atraves do getRowData()

Parece que o spring não esta injetando (HtmlDataTable dataTable) do meu BackingBean.

Alguem já teve este problema???

Olhem as configurações:

Meu BackingBean: CategoryManaged.java

import...
public class CategoryManaged {
    private CategoryBusiness categoryBusiness = null;
    private Category category = new Category();

    private HtmlDataTable dataTable;
    
    /** Creates a new instance of CategoryManaged */
    public CategoryManaged() {
    }
    
    public CategoryBusiness getCategoryBusiness() {
        return categoryBusiness;
    }
    
    public void setCategoryBusiness(CategoryBusiness categoryBusiness) {
        this.categoryBusiness = categoryBusiness;
    }
    
    public Category getCategory() {
        return category;
    }
    
    public void setCategory(Category category) {
        this.category = category;
    }
    
    
    /* Actions -----------------------------------------*/
    
    public String save(){
        categoryBusiness.createCategory(category);
        return SUCESS;
    }
    
    public String cancel(){
        return CANCEL;
    }
    
    public String delete(){        
        System.out.println("Executou delete");
        
        if (dataTable == null){
            System.out.println("dataTable é nulo");
        }else{
            category categ = (category) dataTable.getRowData();
            categoryBusiness.deleteCategory(categ);
        }
                
        return SUCESS;
    }
    
    public List<Category> getCategories(){
        if (categoryBusiness == null){
            return null;
        }else{
            return categoryBusiness.listAllCategory();
        }
    }

    public HtmlDataTable getDataTable() {
        return dataTable;
    }

    public void setDataTable(HtmlDataTable dataTable) {
        System.out.println("setDataTable");
        this.dataTable = dataTable;
    }
}

Uma solução simples:

Cria um <f:param/> no commandButton, na tua action pega o parametro via request.

Itera a getCategories() e remove o elemento.
