RadioGroupItem valueIcons and no value

[bebo]

Im wondering if its possible to use radioGroupItem.setValueIcons().
I guess this should work, but it doesnt:

LinkedHashMap<String, String> values = new LinkedHashMap<String, String>();
values.put("0", "Place");
values.put("1", "Event");
radioGroupItem = new RadioGroupItem("type", "Type");
radioGroupItem.setValueMap(values);
radioGroupItem.setImageURLPrefix("nere/type_");
radioGroupItem.setImageURLSuffix(".png");
LinkedHashMap<String, String> valueIcons = new LinkedHashMap<String, String>();
valueIcons.put("0", "place");
valueIcons.put("1", "event");
radioGroupItem.setValueIcons(valueIcons);

Also, how, if possible, to unselect all the radio values?
Once radioGroupItem.setValue("1") is called, there's a way to come back at initial radioGroupItem draw status, where no option is selected?

I tried it in SmartGWT 2.4 and 6/5 night build.

try radioGroupItem.clearValue();
