DetailViewer doesn't show detail field?

[knguyen]

Hi,

I'm trying to get DetailViewer to show the detail field from a datasource. Here is the code.

    DataSourceTextField firstName = new DataSourceTextField("firstName", "First Name");    
    
    DataSourceTextField lastName = new DataSourceTextField("lastName", "Last Name");
    lastName.setDetail(true);    
    
    DataSource ds = new DataSource();
    ds.setClientOnly(true);
    ds.setFields(firstName, lastName);
    
    DetailViewer viewer = new DetailViewer();
    viewer.setDataSource(ds);
    viewer.setUseAllDataSourceFields(true);
    
    ListGridRecord data = new ListGridRecord();
    data.setAttribute("firstName", "John");
    data.setAttribute("lastName", "Smith");

    viewer.setData(data);
    viewer.draw();

I set lastName to be a detail field, but it doesn't show on DetailViewer.

Please help.
