How to use requestfactory: With (propertyrefs) to combine objects

I'm new to GWT. I need your professional advice

My question is how to use requestfactory: With (propertyrefs) to implement the "tree" structure when these propertyrefs themselves contain the list of items I want to retrieve

Some details:

On the server side, I have four hierarchies of domain objects a, B, C and D:

>An object contains (or I'd better say keep reference) list > B contains list > C contains list

All domain objects mentioned have corresponding proxy interfaces aproxy, bpproxy, cproxy and dpproxy, which are used on the client

On the client side, I want to get the hierarchy of all objects by requesting aproxy objects at once, so I will benefit from the ease of data access using the "get" method, and I have no obligation to make circular server requests for each sub object, sub sub object, etc

Due to specification! I should use smth Like With ("attribute ref") to get a hierarchy, but how to retrieve the combination of the following levels (in my case, each object B in the list and each object C in the list)

Thank you in advance

Solution

We can use form With ("A.B", "A.B.C") for hierarchical combination
