Question

I use DataSource generated from xsd schema. I need to get all fields from DataSource, also nested ones. My problem is the same like in this topic from Smartclient forum forum, when I use DataSource.getFields() its return only first level fields.

Does anyone know how can I get also nested fields?

Answer 1

I found solution. To get nested fields it’s possible to use DataSource.getDataSource(ID). For example, if dataSource is main DataSource, it can be done like that:

    private List<DataSourceField> getAllFields(DataSource dataSource)
    {
        List <DataSourceField> fieldList = new ArrayList<DataSourceField>();
        DataSourceField [] fields = dataSource.getFields();
        fieldList.addAll(Arrays.asList(fields));
        for (DataSourceField field : fields);
        {
            String fieldName = field.getName();
            DataSource ds = DataSource.getDataSource(fieldName);
            if (ds != null)
            {
                fieldList.remove(field);
                DataSourceField[] nFields = ds.getFields();
                fieldList.addAll(Arrays.asList(nFields));
                getAllFields(ds);
            }
        }
        return fieldList;
    }
