Working with complex types of datacontrol

Question

Hi ADF Experts,
I am using JDev 11.1.1.7.0
My requirement is I have a POJO which contains as below
public class OrderProposalReadClient {
    public OrderProposalReadClient() {
        super();
    private String purchaseUnit;
    private BigDecimal stock;
    //  private XMLGregorianCalendar deliveryDate;
    private String deliveryDate;
    private ArrayList<String> openOrders;
    private BigDecimal minStock;
    private ArrayList<String> promotions;
   //getters and setters
I have another java class whose return type is of List<OrderProposalReadClient> and this is exposed as Data Control.
Now thing is that from the Data Control If I drag the return type as table. I do not find the ArrayList elements.
In DataControl the structure is as such.
returnOrderProposalReadClient
-purchaseUnit
-stock
-deliveryDate
-minStock
-promotions
-element
-openOrders
-element
SO when I drag I dont get these 2 elements(promotions and openorders). I tried to follow Shay's blog but didn't find any helpful solution.
My requirement the table should contain all the elements. And if promotions and open Orders are more than 1 then I should see 2 recored with rest values same.
Please help.
Thanks,
Animesh

Hi,
this is because
   private ArrayList<String> openOrders;
doesn't return a collection of POJO but Strings. Try
   private ArrayList<OrderStrings> openOrders;
and create a class
  public class OrderStrings (){
      private String openOrders;
      public void setOpenOrders(String s){this.openOrders = s;}
      public String getOpenOrders(){return this.openOrders} 
This should do the trick
