radiogroupitem sends the same request parameter twice

I am currently testing SmartClient included in SmartGWT 2.0 with the FF 3.6.13.
I've noticed that RadioGroupItem sends the same request parameter twice on DynamicForm.submit().
After I selected USA and pressed "Submit" I got
rdgCountry=usa&rdgCountry=usa in the content of the request

	isc.DynamicForm.create( {
		canSubmit : true,
		action : "PrintParamsServlet",
		method : "POST",
		items : [ {
			name : "rdgCountry",
			type : "radioGroup",
			valueMap : {
				usa : "USA",
				poland : "Poland",
				germany : "Germany"
			}
		}, {
			name : "btnSubmit",
			type : "submit",
			onclick : function(form, item) {
				form.submit();
			}
		} ]
	});

if I remove the editor type declaration from the rdgCountry definition,
selectitem appears and everything works as expected.

isc.DynamicForm.create( {
		canSubmit : true,
		action : "PrintParamsServlet",
		method : "POST",
		items : [ {
			name : "rdgCountry",
			valueMap : {
				usa : "USA",
				poland : "Poland",
				germany : "Germany"
			}
		}, {
			name : "btnSubmit",
			type : "submit",
			onclick : function(form, item) {
				form.submit();
			}
		} ]
	});
