FilterBuilder & ComboBoxItem
Hi,
Docs says that FilterBuilder is using editor type according to the Datasource type. I explicitly set field.setEditorType to ComboBoxItem as in code below. What I want is a drop down list of already entered values in the "continent" field. Although this works in grid row editing mode and in grid filter, it does not work in FilterBuilder. When choosing "continent" field in the FilterBuilder type of value is changed to the ComboBox but drop down list is empty. Does FilterBuilder support ComboBoxItem filled by this.DataSource ? Code:

* To change this template, choose Tools | Template Manager
* and open the template in the editor.

Explicitly set optionDataSource. Using the surrounding form's DataSource as an optionDataSource is a default behavior for forms but not FilterBuilder.

Setting optionDataSource explicity before ds.setFields() (as in following code) causes an error:
Error: Fields cannot be added to a DataSource after the underlying component has been created. Code:
public void onModuleLoad() {
DataSource ds = new DataSource();
ds.setDataFormat(DSDataFormat.XML);
ds.setRecordXPath("/List/country");
ds.setDataURL("data.xml");
DataSourceIntegerField pkField = new DataSourceIntegerField("pk");
pkField.setHidden(true);
pkField.setPrimaryKey(true);
DataSourceTextField countryCodeField = new DataSourceTextField("countryCode", "Code");
countryCodeField.setRequired(true);
DataSourceTextField countryNameField = new DataSourceTextField("countryName", "Country");
countryNameField.setRequired(true);
DataSourceTextField capitalField = new DataSourceTextField("capital", "Capital");
DataSourceTextField governmentField = new DataSourceTextField("government", "Government", 500);
DataSourceBooleanField memberG8Field = new DataSourceBooleanField("member_g8", "G8");
DataSourceTextField continentField = new DataSourceTextField("continent", "Continent");
//continentField.setValueMap("Europe", "Asia", "North America", "Australia/Oceania", "South America", "Africa");
ComboBoxItem comboBoxItem = new ComboBoxItem("continent");
comboBoxItem.setOptionDataSource(ds);
continentField.setEditorType(comboBoxItem);
DataSourceDateField independenceField = new DataSourceDateField("independence", "Nationhood");
DataSourceFloatField areaField = new DataSourceFloatField("area", "Area (km²)");

ds.setFields(pkField, countryCodeField, countryNameField, capitalField, governmentField,
memberG8Field, continentField, independenceField, areaField, populationField,
gdpField);
FilterBuilder filterBuilder = new FilterBuilder();
filterBuilder.setDataSource(ds);

grid.setDataSource(ds);
grid.setAutoFetchData(true);
grid.setWidth(550);
grid.setHeight(224);

VLayout main = new VLayout();
main.addMember(filterBuilder);

}

A solution
Add this code to your datasource class (in my case it was the user datasource)
Code:
final DataSourceIntegerField office = new DataSourceIntegerField("officeId", "Office Location");
office.setEditorType(new ComboBoxItem());
OfficeDS.getInstance().fetchData(null, new DSCallback(){
@Override
public void execute(DSResponse response, Object rawData, DSRequest request) {
office.setValueMap(response.getDataAsRecordList().getValueMap("id", "name"));
}});
