Get GWT value in servlet

Question

I got a headache in which it turns out how to extract the values ​​of the gwt radio buttons on the server side.

Here is my form of UiBinder:

<g:FormPanel ui:field="form"><g:VerticalPanel ui:field="fruitPanel">
    <g:RadioButton name="fruit">apple</g:RadioButton>
    <g:RadioButton name="fruit">banana</g:RadioButton>
    <g:SubmitButton>Submit</g:SubmitButton> ...

This is how I initialize the form:

form.setAction("/submit");
form.setMethod(FormPanel.METHOD_POST);

So, although I would have to do this on a servlet:

fruit = req.getParameter("fruit")

But of course this does not work, the fruit parameter does not exist: /

Edit: Ok I get the parameter, but it is always "on"

I also tried adding a switch in java with:

RadioButton rb0 = new RadioButton("fruit", "apple");
RadioButton rb1 = new RadioButton("fruit", "banana");
fruitPanel.add(rb0);
fruitPanel.add(rb1);

Edit: this is a GWT problem : Problem 4795
