SuggestBox, Oracle and uibinder

Hi, I have been dealing with a problem which seems to me not having a clean solution.

I have declared a SuggestBox in uibinder:

<g:SuggestBox ui:field="suggestBox" height="32px" width="550px"></g:SuggestBox>

Then, I can populate the already provided SuggestBox on the View:

        MultiWordSuggestOracle oracle = (MultiWordSuggestOracle) suggestBox.getSuggestOracle();

        oracle.add("Afghanistan");

It works correctly. However, in my case I need a server side call to fetch the suggested values. And then the problems arise.

1* On one hand the suggestBox.setOracle() method is not accessible so I cannot provide a new Oracle to the created instance

2* If I try to create a new instance before the bean is instantiated (as I read somewhere), i.e.:

suggestBox = new SuggestBox(createOracle(new MultiWordSuggestOracle()));

System.out.println("before:" + suggestBox.getSuggestOracle().toString());

        initWidget(uiBinder.createAndBindUi(this));

System.out.println("after:" + suggestBox.getSuggestOracle().toString());

I see that the oracle instance after is different to oracle instance before, so the createAndBindUi method instantiates and assigns a new instance.

3* I do not think I can assign an oracle instance on declaring SuggestBox on uibinder (i.e. XML)

4* Probably I create a new class extending SuggestBox with a custom Oracle and declare this new class on uibinder but it looks unnecessarily complicated

5* And the only thing that I figure out is declaring a place holder for the SuggestBox in the uibinder (e.g. an <g:HTMLPanel ui:field="placeholder"/>) and programmatically add my SuggestBox with my custom oracle on the View class. Then I would not be using the uibinder to declare SuggestBox.

So, the question is: how to change the Oracle for a SuggestBox declared in uibinder? Any experience?

Thanks
