Hi,
My classess are
@PersistenceCapable(identityType = IdentityType.APPLICATION,
detachable = "true")
public class Type implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private String name;
@Persistent(mappedBy = "type")
@Element(dependent = "true")
private List<Product> products = new ArrayList<Product>();
//getter-setter
}
and
@PersistenceCapable(identityType = IdentityType.APPLICATION,
detachable = "true")
public class Product implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private String name;
@Persistent(defaultFetchGroup = "true")
private Type type;
//getter-setter
}
when adding a product to type, ı am using
PersistenceManager pm =
PMF.get().getPersistenceManager();
try {
Product product = new
Product("Sample product");
Type type =
pm.getObjectById(Type.class, selected.getKey());
type.getProducts().add(product);
pm.makePersistent(type);
} finally {
pm.close();
}
is working and adding a product to type
I am using this code when i want to change type of product
PersistenceManager pm =
PMF.get().getPersistenceManager();
try {
Product product =
pm.getObjectById(Product.class, currentProduct.getKey());
Type type =
pm.getObjectById(Type.class, selectedType.getKey());
product.setType(type);
pm.makePersistent(product);
} finally {
pm.close();
}
But it's not working and no throws any error. How can i update Type of
Product
Thanks
Ertan
