column in listview that is combination of two fields

2009-11-10 Thread Swarnim Ranjitkar 

 I have a ListView with a requirement that I display one one the column as 
combination of two fields eg. my cnameID should be cname:id.
 Is there a way to get the model so that it is Label is combination of two 
fields or do I have to create a wrapper object for this purpose.
 
 ListView = new ListView(test, testList) {
  @Override
  protected void populateItem(ListItem item) {
TestObject testObj = (TestObj) item.getModelObject();
item.add(new Label(Name, new PropertyModel(testObj, name)));
//second column should be cname:id
   item.add(new Label(cnameID, new PropertyModel(testObj, cname)));
   
 public class TestObj{
 public String name;
 public int id;
 public String cname;
 }
 thank you

I think you can use an AbstractReadOnlyModel like:
getObject{
return testObj.getCname()+testObj.getId();
}

  public class TestObj{
