RadioGroupItem with Boolean values

[yves_bussard]

I use a RadioGroupItem with two values. The value map uses Boolean values rather than String to map a value to the corresponding option. The first time the value is set the option is correctly displayed. But if I try to change it to a new value it clears the options leaving me with an empty RadioGroupItem. I think it is only a display problem, the value seems to be correct.

I tried this with the Version 5.0p (2014-09-14) and GWT 2.6.1. Upgrading to the latest nightly build of smartgwt does not help. I had an old version of smartgwt from the year 2013 which works as indented. But unfortunately, I don't know which version that is since it is a dummy project and not under source control.

Below is a standalone test case. As mentioned before the initial value is displayed correctly. Once you press the switch-button though the RadioGroupItem displays nothing. Sometimes the correct value is displayed for a fraction of second before cleared.

If I replace the Boolean values in the value map with Strings ("true" and "false") and set a String value (String.valueOf(this.flag)) instead of a Boolean value, then it works. This is the workaround I've currently implemented (and which I consider ugly).

import java.util.LinkedHashMap;

import com.google.gwt.core.client.EntryPoint;
import com.smartgwt.client.data.Record;
import com.smartgwt.client.widgets.Button;
import com.smartgwt.client.widgets.events.ClickEvent;
import com.smartgwt.client.widgets.events.ClickHandler;
import com.smartgwt.client.widgets.form.DynamicForm;
import com.smartgwt.client.widgets.form.ValuesManager;
import com.smartgwt.client.widgets.form.fields.RadioGroupItem;
import com.smartgwt.client.widgets.layout.VLayout;

public class Test implements EntryPoint {
	
	private static final String FIELD_RADIO = "radio";
	private boolean flag = false;

	@Override
	public void onModuleLoad() {
		VLayout layout = new VLayout();
		final ValuesManager mgr = new ValuesManager();
		
		DynamicForm form = new DynamicForm();
		form.setValuesManager(mgr);
		
		RadioGroupItem item = new RadioGroupItem(FIELD_RADIO, "Do you like cookies?");
		item.setWrapTitle(Boolean.FALSE);
		// Value map for possible options
		LinkedHashMap<Object, String> map = new LinkedHashMap<Object, String>();
		map.put(Boolean.TRUE, "Yes");
		map.put(Boolean.FALSE, "No");
		item.setValueMap(map);
		item.setVertical(false);
		
		form.setFields(item);
		editWithNewValueForFlag(mgr);
		layout.addMember(form);
		
		Button button = new Button("switch");
		button.addClickHandler(
			new ClickHandler() {
				
				@Override
				public void onClick(ClickEvent event) {
					Test.this.flag = !Test.this.flag;
					editWithNewValueForFlag(mgr);
				}
			}
		);
		layout.addMember(button);
		layout.draw();
	}

	private void editWithNewValueForFlag(final ValuesManager mgr) {
		Record record = new Record();
		record.setAttribute(FIELD_RADIO, Boolean.valueOf(this.flag));
		mgr.editRecord(record);
	}

}

Thanks for letting us know about this problem. We have just fixed the issue, you will find the fix applied in the next nightly build.

Thank you

Thank you very much for the fix. I can confirm that it works now in my environment.
