RPCProxy and gwt-dispatch

Show key headers only | View raw

Hi!
I'm trying to do a little something in GXT and I want to use List from
GXT and RPCProxy.
Let's say I have a bean class of Foo. I have an action called
ListFooAction and result associated with it - ListFooResult.
ListFooAction is empty, since I want to list all my Foo's, and
ListFooResult contains a list of all Foo objects - List<Foo>.
Now what I'd like to do, is to load my foo objects using gwt-dispatch
inside RPCProxy load method. After looking into GXT list examples, I
assume my RPCProxy should be like this: RPCProxy<List<Foo>>. I have to
provide implementation for abstract method - load:

Override
protected void load(Object loadConfig,  AsyncCallback<List<Foo>> callback) {

     }
};

Now I'd like to execute my ListFooAction using DispatchAsync inside that
method to load all my Foo objects. Doing so, I would have an
AsyncCallback<ListFooResult>. But RPCProxy load method has
AsyncCallback<List<Foo>>, and I have List<Foo> inside my FooResult. How
can I "transfer" list from my result to the callback from the load
method? Is this possible? Or maybe there is better approach to achieve
what I'm trying to do?

Regards
