SimpleFromController and binding multiple objects

[riboriori]

Hi all,
this is my first post on this forum, and i'm new to spring.
I'm developing a simple page, in wich i put some input field as criteria for searching results on a db.
The problem is that the input fields are related to differerent properties on hibernate pojo, on my domain package.
(i'm using annotations).
I'm confusing about binding at jsp-level, when i've multiple beans as a single command object.
I've maked another class that i calles "Entities", wich has my hibernate pojo as properties, in wich i addedd canonical getters and setters.
In my jsp i've used the <srping:bind> tags, so, for example:

<spring:bind path="command.user.userName">
<input type="text" name = userName"/>
</spring:bind>

(Suppose that in my jsp there are other fields, related to other pojos, as departements and so on).


I've noticed that in my overrided OnSubmit method, if i get the Entities object as:

Entities entity = (Entities) command;
System.out.println(entity.getUser.getUserName);

The System.out.println produces a null value: this is because the binding does not happens.

So i must override the formBackingObject method and:
User user = new User();
Entities entity = new Entity();
user.setUserName(request.getParameter("userName")) ;
entity.setUser(user);
return entity;

In this way it works, but i must "force" to insert the correct values into the entities class, by processing the request.
There is a way in order to populate automatically my Entities class (and related sub-objects, as User object, Departements object)?

Other infos:
1) In my spring definition of controller, i've settes the commandClass to Entities class.
2) form view and success view are different.
Can someone help me??

Best regards

Hi riboriori,

Plz have a look at the chapter 14 of spring doc
http://static.springframework.org/spring/docs/2.5.x/reference/view.html"


The SimpleFormController takes care of binding of the subobjects also.
