BAPI Table Input not passing to R/3 Backend

Question

Hello Experts,
I am having trouble populating a Table input in my Web Dynpro Java application.  I have tried researching this issue on SDN and have attemped many of the solutions with no luck.  Here is my code:
          Bapi_Order_Input NewOrder = new Bapi_Order_Input();
          wdContext.nodeBapi_Order_Input().bind(NewOrder);
          Bapisdhd1 OrderHead = new Bapisdhd1(); - <i>(This is part of the Input Paramter, values are successfully passed)</i>
          OrderHead.setDoc_Type("ZOR");
          OrderHead.setSales_Org("2000");
          OrderHead.setDistr_Chan("40");
          NewOrder.setOrder_Header_In(OrderHead);                    
          Bapiparnr Partner = new Bapiparnr(); - <i>(This is a table parameter, values are not being passed to the backend)</i>
          Partner.setPartn_Role("SP");
          Partner.setPartn_Numb("20010");
          Partner.setItm_Number("000000");     
          NewOrder.addOrder_Partners(Partner);
          wdContext.currentBapi_Salesorder_Createfromdat2_InputElement().modelObject().execute();
I cannot use "NewOrder.setOrder_Partners(Partner)" because Order_Partners is an AbstactList.  I have attempted to create this abstract list below but it will not syntactically check:  
AbstractList PartnerList = new Bapiparnr.Bapiparnr_List();
If I test these same input values above in R/3, the BAPI executes fine.  When I test the BAPI from WD, I get the return message " Please enter a Sold-To or ShipTo Party".  I can replicate this same message in R/3 if I do not populate the Partner table.
I am also able to see the Partner values I enter when I create a Table is display them in Web Dynpro.
This is frusterating me a great deal and I would greatly appreciate, and rewards, any suggestions or recomendations.
Thank you for your help,
Matt

Hi Everyone,
Well, I was finally able to resolve my issue.  After debugging the Web Dynpro Application from the ECC BAPI side, I was able to see that the Partner values were failing to be passed to the back-end SAP system.  After I restarted the J2EE engine, I was able to create the sales order.
I noticed a couple of interesting things as well:
-You need to fill in the leading zeros for Customer Number (KUNNR) before passing of this value
-The ECC BAPI automatically (atleast in my case) changed the input value of Partner-PartnerRole from "SP" to "AG".  This change occurs before the first step in the Debugger is performed.  This change, however, does not occur when the BAPI is called from Web Dynpro.  Once I edited the Web Dynpro Partner Role input to "AG", I was able to create the sales order.
I have list my code below, thank you all for your help.
