    ExportFormat.OOXML

    Hi Isomorphic,

    please take a look at this test case (v12.0p_2019-10-06/PowerEdition Deployment (built 2019-10-06)).

    Code:
    package com.smartgwt.sample.client;
    
    import com.google.gwt.core.client.EntryPoint;
    import com.smartgwt.client.Version;
    import com.smartgwt.client.core.KeyIdentifier;
    import com.smartgwt.client.data.DSRequest;
    import com.smartgwt.client.types.ExportFormat;
    import com.smartgwt.client.util.Page;
    import com.smartgwt.client.util.PageKeyHandler;
    import com.smartgwt.client.util.SC;
    import com.smartgwt.client.widgets.Button;
    import com.smartgwt.client.widgets.IButton;
    import com.smartgwt.client.widgets.Window;
    import com.smartgwt.client.widgets.events.ClickEvent;
    import com.smartgwt.client.widgets.events.ClickHandler;
    import com.smartgwt.client.widgets.grid.HeaderSpan;
    import com.smartgwt.client.widgets.grid.ListGrid;
    import com.smartgwt.client.widgets.grid.ListGridField;
    import com.smartgwt.client.widgets.layout.VLayout;
    
    public class BuiltInDS extends VLayout implements EntryPoint {
        private IButton recreateBtn;
    
        public void onModuleLoad() {
            KeyIdentifier debugKey = new KeyIdentifier();
            debugKey.setCtrlKey(true);
            debugKey.setKeyName("D");
    
            Page.registerKey(debugKey, new PageKeyHandler() {
                public void execute(String keyName) {
                    SC.showConsole();
                }
            });
    
            setWidth100();
            setHeight100();
    
            recreateBtn = new IButton("Recreate");
            recreateBtn.addClickHandler(new ClickHandler() {
                @Override
                public void onClick(ClickEvent event) {
                    new MyWindow().show();
                }
            });
            addMember(recreateBtn);
            new MyWindow().show();
            draw();
        }
    
        private class MyWindow extends Window {
            public MyWindow() {
                setWidth(400);
                setHeight(300);
                setMembersMargin(0);
                setModalMaskOpacity(70);
                setTitle(" (" + Version.getVersion() + "/" + Version.getSCVersionNumber() + ")");
                setShowMinimizeButton(false);
                setIsModal(true);
                setShowModalMask(true);
                centerInPage();
    
                final ListGrid exportGrid = new ListGrid();
                exportGrid.setDataSource("animals");
    
                ListGridField commonNameLGF = new ListGridField("commonName");
                ListGridField scientificNameLGF = new ListGridField("scientificName");
                ListGridField lifeSpanLGF = new ListGridField("lifeSpan");
                ListGridField statusLGF = new ListGridField("status");
    
                HeaderSpan headerSpan = new HeaderSpan("HeaderSpan", new String[] { "scientificName", "status" });
                exportGrid.setHeaderSpans(headerSpan);
    
                exportGrid.setFields(commonNameLGF, scientificNameLGF, lifeSpanLGF, statusLGF);
                exportGrid.fetchData();
    
                Button exportButton = new Button("Export_data");
                exportButton.addClickHandler(new ClickHandler() {
                    @Override
                    public void onClick(ClickEvent event) {
    
                        final DSRequest exportRequest = new DSRequest() {
                            {
                                setExportAs(ExportFormat.OOXML);
                            }
                        };
                        exportGrid.exportData(exportRequest);
                    }
                });
    
                addMember(exportGrid);
                addMember(exportButton);
            }
        }
    }
    When I export the data, I get an error
    Code:
