title: How to work with GXT Grid?
body: <p>I have a DTO object with fields:</p>
  
  <pre><code>public class EmpDTO extends BaseModel implements java.io.Serializable {
      private short empno;
      private EmpDTO emp;
      private DeptDTO dept;
      private String ename;
      private String job;
  </code></pre>
  
  <p>I try output this class in the grid:</p>
  
  <pre><code>List&lt;ColumnConfig&gt; configs = new ArrayList&lt;ColumnConfig&gt;();
  ColumnConfig clmncnfgEname = new ColumnConfig("ename", "ename", 150);
  configs.add(clmncnfgEname);
  ListStore&lt;EmpDTO&gt; store = new ListStore&lt;EmpDTO&gt;();
  EmpDTO empDTOtmp = new EmpDTO();
  empDTOtmp.setEname("Name");
  store.add(empDTOtmp);
  Grid&lt;EmpDTO&gt; grid = new Grid&lt;EmpDTO&gt;(store, new ColumnModel(configs));
  mainContentPanel.add(grid);
  </code></pre>
  
  <p>But i see empty grid with out error. How to fix this?</p>
