Question

I have a DTO object with fields:

public class EmpDTO extends BaseModel implements java.io.Serializable {
    private short empno;
    private EmpDTO emp;
    private DeptDTO dept;
    private String ename;
    private String job;

I try output this class in the grid:

List<ColumnConfig> configs = new ArrayList<ColumnConfig>();
ColumnConfig clmncnfgEname = new ColumnConfig("ename", "ename", 150);
configs.add(clmncnfgEname);
ListStore<EmpDTO> store = new ListStore<EmpDTO>();
EmpDTO empDTOtmp = new EmpDTO();
empDTOtmp.setEname("Name");
store.add(empDTOtmp);
Grid<EmpDTO> grid = new Grid<EmpDTO>(store, new ColumnModel(configs));
mainContentPanel.add(grid);

But i see empty grid with out error. How to fix this?

Answer 1

Do you have to use BaseModel? Rather than extending BaseModel why not implement BeanModelTag?

public class EmpDTO implements BeanModelTag {

Otherwise make sure setEname looks like this:

public void setEname(String ename) {
  set("ename",ename);
}

And getEname looks like this:

public String getEname() {
   return (String)get("ename");
}
