How to give AbstractList argument for data binding

Hi All,

I want to create a Purchase Requisition from my WebDynPro form.

I have imported the BAPI_PR_CREATE.

I have created a Custom Controller where the Context looks like

Bapi_Pr_Create_Input

-

---

PrHeader

-

---

PrHeadertext

-

---

PrHeaderx

-

---

PrItem

-

---

PrItemtext

-

---

PrItemx

Foll is my code in the method executeBapiPRCreate()

Bapi_Pr_Create_Input prCreateInput = new Bapi_Pr_Create_Input();

wdContext.nodePR_Creation().bind(prCreateInput);

Bapimereqitem itemInput = new Bapimereqitem();

Bapimereqitemx itemInputX = new Bapimereqitemx();

Bapimereqitemtext itemtextInput = new Bapimereqitemtext();

Bapimereqheader headerInput = new Bapimereqheader();

Bapimereqheaderx headerInputX = new Bapimereqheaderx();

Bapimereqheadtext headtextInput = new Bapimereqheadtext();

itemInput.setAcctasscat("U");

itemInput.setPreq_Name("NikhilBansal");

itemInput.setMaterial("000000000000034621");

itemInput.setPlant("0002");

itemInput.setPur_Group("RD3");

itemInput.setMatl_Group("COMPDT");

itemInput.setPurch_Org("STPO");

itemInput.setStore_Loc("SB01");

itemInput.setTrackingno("LOUB0101");

itemInput.setQuantity(new BigDecimal("01"));

itemInputX.setAcctasscat(true);

itemInputX.setPreq_Name(true);

itemInputX.setMaterial(true);

itemInputX.setPlant(true);

itemInputX.setPur_Group(true);

itemInputX.setMatl_Group(true);

itemInputX.setPurch_Org(true);

itemInputX.setStore_Loc(true);

itemInputX.setTrackingno(true);

itemInputX.setQuantity(true);

itemtextInput.setText_Line("Text Line 1");

headerInput.setPr_Type("NB");

headerInputX.setPr_Type(true);

headtextInput.setText_Line("Text Line 2 ");

wdContext.nodePrheader().bind(headerInput);

wdContext.nodePrheadertext().bind(headtextInput);

prCreateInput.setPrheader(headerInput);

prCreateInput.setPrheaderx(headerInputX);

<b>However, when I try this line

prCreateInput.setPritem(itemInput);</b>

then I get compilation error : AbstractList argument expected.

Can someone tell me what should I do give argument of type AbstractList.

Plz help.
