public class A extends BaseModelData implements BeanModelTag { ... }
public class B extends BaseModelData implements BeanModelTag { ... }
final BeanModelFactory factoryA = BeanModelLookup.get().getFactory(A.class); // return null
final BeanModelFactory factoryB = BeanModelLookup.get().getFactory(B.class); // return null
why return null?

did you solve it? thank

If you extend BaseModelData there is no need to implement BeanModelTag. You just need one of both.

Hi this is my bean class
public class PaymentDTO extends BeanModel implements Serializable{
public final static String DESCRIPTION = "description";
public final static String ID = "id";
public final static String ENABLED = "enabled";
public PaymentDTO() {
}
public PaymentDTO(Integer id, String description, Boolean enabled) {
set(ID,id);
set(DESCRIPTION, description);
set(ENABLED, enabled);
}
..
when I try to add new record I use this code
BeanModelFactory factory = BeanModelLookup.get().getFactory(PaymentDTO.class);
if(factory == null){
MessageBox.alert("factory", "factory == null", null);
}
selectedModel = factory.createModel(new PaymentDTO(1, "civera", true));
factory is always null
selectedModel is an object that incapsulate current record....
I declare it like this:
private Grid<BeanModel> grid = null;
private ListStore<BeanModel> store;
private BeanModel selectedModel;

thank in advance estefan civera
Its not correct.
Instead of extending BeanModel you need to extend BaseModel and you also dont have to use BeanModelLookup at all.

What I do is (I pass objects back and forth via Gilead / Hibernate)
1. get POJO (that implements BeanModelTag)
2. Use BeanModelFactory to generate the BeanModel lets call it myModel
3. Use myModel.getBean() when I am ready to send it back to the server
In your case since your DTOs are already using get() and set() BaseModel style getters and setters why dont you just pass the DTO back to the server as is?
