How to use RequestFactory: .with(propertyRefs) for composition of objects

[basilboli]

Hello, 

I am newbie to GWT and  I need your professional advice.

My question is : 

how to use RequestFactory: .with(propertyRefs) for kind of “tree” structures when 

these propertyRefs itself contains list of items I would like to retrieve.

Some details: 

On the server-side I have hierarchy of four domain objects A,B,C,D:

• A object contains (or I'd better say keep reference to)  List <B>
  
• B contains List <C>
  
• C contains List <D>.

All mentioned domain objects have its corresponding proxy interfaces AProxy, BProxy, CProxy, DProxy to use on the client side.

On the client side I would like to get all that hierarchy of objects

by once requesting AProxy object so I would profit from the easiness of data access using “get” methods and wouldn’t be obliged to make looping server requests for every sub-object, sub-sub-objects etc.

Due to specification I should use smth. like  .with(“property ref”) to get one level of hierarchy 

but what about retrieving following levels of compositions (in my case List <C> for every object B and List<D> for every object C).

Thanks in advance.

Hi there:

Assuming that your lists are named listB, listC, listD, then you would
write:
.with ("A.listB", "A.listB.listC", "A.listB.listC.listD")
to cause your various proxies to be populated by a single call to the
server.

Hope that helps,
Ryan

The .with method accepts a string array via variable arguments. So you can write .with("a.b", "a.b.c", "a.b.c.d"). If you use RequestFactoryEditorDriver there is also a method called getPath() with returns the correct path array needed by your editors.
