setExportFieldTitles() not working

[edulid]

setExportFieldTitles() seems not to work. I still get the "name" title in the excel file, while I should get "name abc abc".
This was working in previous versions.
Using smartgwt 6.0p 06.04.16 power.

public void onModuleLoad() {

        final VLayout vlayout = new VLayout();

        final ListGrid lg = new ListGrid();
        ListGridField nameField = new ListGridField("f_name", "name");
        lg.setFields(nameField);
        lg.setDataSource("schueler_table");
        lg.fetchData();

        IButton but = new IButton("click me");
        but.addClickHandler(new ClickHandler() {

            @Override
            public void onClick(ClickEvent event) {
                DSRequest properties = new DSRequest();
                properties.setExportFilename("Export");
                properties.setExportAs(ExportFormat.XLS);
                properties.setOperationId("fetch_test");
                properties.setExportDisplay(ExportDisplay.DOWNLOAD);
                lg.exportData(properties);
            }
        });
        
        vlayout.addMember(lg);
        vlayout.addMember(but);
        vlayout.setWidth100();
        vlayout.setHeight100();
        vlayout.draw();

    }

schueler_table.ds.xml:

<DataSource ID="schueler_table">

    <fields>
        <field name="f_name" type="text" />
    </fields>

    <operationBindings>

        <operationBinding operationType="fetch" operationId="fetch_test">
            <serverObject className="de.mks_infofabrik.kids.server.test.TestingDMI"
                methodName="testMethod" />
        </operationBinding>

    </operationBindings>


</DataSource>

TestingDMI:

public class TestingDMI {

    private static final Logger LOG = Utils.getLogger(TestingDMI.class);

    public DSResponse testMethod(DSRequest dsRequest) throws Exception {

        LOG.info("TestingDMI: ExecuteMethod()");

        Map<String,Object> originalTitles = dsRequest.getExportFieldTitles();

        originalTitles.put("f_name", "name abc abc");
        
        dsRequest.setExportFieldTitles(originalTitles);

        return dsRequest.execute();
    }
}
