Bug in RadioGroupItem.setDefaultValue(Enum) (with minimal testcase)

[Blama]

Hi Isomorphic,

I'm using RadioGroupItem with a valuemap with an enum as key. This works very well. But if I try to set a defaultvalue, I get an exception with very little details.
I'm using v9.0p_2014-01-13/EVAL Deployment and Development Mode from Eclipse with GWT 2.5.1 (tested with 2.6.1-rc3, too).

Please change the builtInDs example as follows to reproduce:

package com.smartgwt.sample.client;

import java.util.LinkedHashMap;

import com.google.gwt.core.client.EntryPoint;
import com.smartgwt.client.core.KeyIdentifier;
import com.smartgwt.client.util.KeyCallback;
import com.smartgwt.client.util.Page;
import com.smartgwt.client.util.SC;
import com.smartgwt.client.widgets.form.DynamicForm;
import com.smartgwt.client.widgets.form.fields.RadioGroupItem;
import com.smartgwt.client.widgets.form.fields.events.ChangedEvent;
import com.smartgwt.client.widgets.form.fields.events.ChangedHandler;
import com.smartgwt.client.widgets.layout.VStack;

/**
 * Entry point classes define <code>onModuleLoad()</code>.
 */
public class BuiltInDS implements EntryPoint {
	private DynamicForm boundForm;
	private LinkedHashMap<MyEnum, String> optionMap;

	public void onModuleLoad() {
		KeyIdentifier debugKey = new KeyIdentifier();
		debugKey.setCtrlKey(true);
		debugKey.setKeyName("D");

		Page.registerKey(debugKey, new KeyCallback() {
			public void execute(String keyName) {
				SC.showConsole();
			}
		});

		VStack vStack = new VStack();
		vStack.setLeft(175);
		vStack.setTop(75);
		vStack.setWidth("70%");
		vStack.setMembersMargin(20);

		boundForm = new DynamicForm() {
			{
				optionMap = new LinkedHashMap<MyEnum, String>();
				optionMap.put(MyEnum.O1, "Option 1");
				optionMap.put(MyEnum.O2, "Option 2");
				optionMap.put(MyEnum.O3, "Option 3");

				final RadioGroupItem myRGI = new RadioGroupItem() {
					{
						setName("Three_options");
						setTitle("Three_options");
						setColSpan("*");
						setRequired(true);
						setVertical(false);
						setRedrawOnChange(true);
						setWidth100();
						setValueMap(optionMap);
						// This line causes an exception:
						setDefaultValue(MyEnum.O1);
					}
				};

				myRGI.addChangedHandler(new ChangedHandler() {
					@Override
					public void onChanged(ChangedEvent event) {
						MyEnum selectedOption = (MyEnum) myRGI.getValue();
						SC.say(selectedOption.getValue());
					}
				});

				setFields(myRGI);
			}
		};
		vStack.addMember(boundForm);
		vStack.draw();
	}

	public enum MyEnum {
		O1("One"), O2("Two"), O3("Three");

		private String value;

		MyEnum(String value) {
			this.value = value;
		}

		public String getValue() {
			return this.value;
		}
	}
}

Exception:
