RE: [Springframework-developer] Spring FormController with multiple commands

[Alef A. <al...@jt...>]

Colin,

I talked about wrapping the command objects in the blog but I guess I =
forgot that I could do it using an inner class as well. This certainly =
makes things much cleaner!=20

About integrating with WebWork, there is a tiny section about the =
integration code in the reference docs. I could put a bit more content =
in there.

I'll spend some time on that tomorrow. I can certainly have a more =
thorough look at WebWork next week or the week after.

rgds,
Alef

Subject: [Springframework-developer] Spring FormController with multiple =
commands
=20
Alef, I was looking at your blog entry about the topic of supporting=20
multiple command objects in the form controllers.
  http://blog.arendsen.net/?p=3D23

I actually think it'd be an excellent idea to take a more exhaustive=20
look at WebWork in terms of plugging any deficiencies in Spring MVC in=20
terms of things that WebWork can do easily which Spring MVC can't.  (at=20
the same time, as I mentioned to Jason Carreirra at TSSJS, I'd like to=20
also make it easier for people to use WebWork with Spring if they really =

want to, by at least pointing to some of the integration code and=20
documenting its existence a bit better).

However, on the subject of supporting binding to multiple command=20
objects, the idiom I've found pretty handy in the case is simply to have =

a static inner class in my controler for this purpose. It's completely=20
trivial to do:

public XXXXX extends AbstractFormController {

  . . .

  public static class Command {
    MyDomainObject myDomainObject =3D new MyDomainObject();
    MyOtherObject myOtherObject =3D new MyOtherObject();

    public MyDomainObject getMyDomainObject() { return myDomainObject }
    public MyOtherObject getMyOtherObject() { return myOtherObject }
  }
}

There's no need for anybody else other than the JSP page or the=20
controller to know about this inner Command class, and code management=20
is super-simple...
