Can not save the foreign key in Spring form Select tag

[Zed Ahmed]

Hi All
I'm trying to save a form that has a foreign key in select tag but it's always null. When I use the inspect element it posts the selected id so I can't say it's problem with form. Can someone please help.

Form

<form:select path="categoryId">
            <form:option value="0" label="   -- Please Select --" />
            <form:options items="${categoryList}"  itemValue="categoryId" itemLabel="categoryName"/>
    </form:select>

Controller

@RequestMapping(value = "product", method = RequestMethod.POST)
public String addNewProduct(@ModelAttribute("product") Product product, Model model){
    model.addAttribute("product", product);
    purchaseOrderService.addProduct(product);
    return "categories";
}

JPA

@Transactional(propagation = Propagation.REQUIRED)
    public boolean saveProduct(Product product) {
        EntityManager em = getEm();
        em.persist(product);
        return true;
    }

Persistence Object

@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name = "CATEGORY_ID", referencedColumnName = "CATEGORY_ID")
private Category categoryId;

Many thanks for your input it helped alot.

<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-core</artifactId>
			<version>4.1.7.Final</version>
		</dependency>
		<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-entitymanager</artifactId>
			<version>4.1.7.Final</version>
		</dependency>

I had these dependencies as 4.1.3. When I updated them it worked.

Well this has got rid of the errors but it has a strange behaviour now, it creates a new category even thou I'm in product controller and trying to save a new product with selected category(FK). Then it adds this newly created categoryId which is duplicate of the one you selected( the name, not the id) into product.categoryId.
I really hope I'm not confusing anyone. I would really appreciate some please.
