[SelectItem] Multiple values in Listgrid - Bug?

[mgandy]

Hello,

I am trying to add a multiple selectItem in a listgrid where the user can edit and select multiple values from a valueMap: 2 values Europe and Asia (see pix attached: test_case0).

If the user selects both values in the selectItem picklist and if she edits again the selectItem,, she has now the choice between Europe and Asia and Europe,Asia (see pix attached: test_case)
I would have expected to have both values Europe and Asia selected but not this new third option...

Test case:
I derived the showcase code "edit by row" to provide you with a test case:

OnModuleLoad:

 
	public static enum Result {EUROPE, ASIA};
	 
	public void onModuleLoad() {

		DataSource worldDS = CountryXmlDS.getInstance();  
		  
        final FilterBuilder filterBuilder = new FilterBuilder();  
        filterBuilder.setDataSource(worldDS);
  
        final ListGrid countryGrid = new ListGrid();  
        countryGrid.setWidth(550);  
        countryGrid.setHeight(224);  
        countryGrid.setDataSource(worldDS);  
        countryGrid.setAutoFetchData(true);  
        
        ListGridField continentField = new ListGridField("continent", "Continent");
        continentField.setCanFilter(true);
        continentField.setMultiple(true);
        
        countryGrid.setFields(continentField);  
  
        IButton filterButton = new IButton("Filter");  
        filterButton.addClickHandler(new ClickHandler() {  
            public void onClick(ClickEvent event) {  
                countryGrid.filterData(filterBuilder.getCriteria());  
            }  
        });  
  
        VStack vStack = new VStack(10);  
        vStack.addMember(filterBuilder);  
        vStack.addMember(filterButton);  
        vStack.addMember(countryGrid);  
  
        vStack.draw();  
	
	}

and the local datasource CountryXmlDS to run the test case:

public class CountryXmlDS extends DataSource {  
  
    private static CountryXmlDS instance = null;  
  
    public static CountryXmlDS getInstance() {  
        if (instance == null) {  
            instance = new CountryXmlDS("countryDS");  
        }  
        return instance;  
    }  
  
    public CountryXmlDS(String id) {  
  
        setID(id);  
        setRecordXPath("/List/country");  
        DataSourceIntegerField pkField = new DataSourceIntegerField("pk");  
        pkField.setHidden(true);  
        pkField.setPrimaryKey(true);  
  
        DataSourceTextField continentField = new DataSourceTextField("continent", "Continent");  
        HashMap<String, String> reportFormatMap = new HashMap<String, String>();
        for (Result reportFormatEnumVal: Result.values())
			reportFormatMap.put(reportFormatEnumVal.name(),  reportFormatEnumVal.name());
        continentField.setValueMap(reportFormatMap);
        continentField.setMultiple(true);
        continentField.setCanEdit(true);
  
        setFields(pkField, continentField);  
  
        setDataURL("ds/test_data/country.data.xml");  
        setClientOnly(true);  
    }  
}

and finally a test record country.data.xml

<List>
<country>
    <continent>Europe</continent>
</country>
</List>

Any ideas?
