Help on the Transactional BAPI - Writing to R/3 BAPI

Question

1)I have imported and created Model for a custom BAPI ZPM_CREATE_ORDER and TRANSACTIONAL BAPIs i.e., COMMIT & ROLLBACK bapis.
2)I have mapped the context from Model to Custom Controller and then to View Controller. Also, did the UI Element Binding.
3) Added the methods callBapi_Create_Order and callBapi_Transaction_Commit which contain the Bapi executin in Cust Controller.
But nothing happening if I click on the Create Order button of the View.
My onActionCreateOrder() Method contains just 2 lines of code 1) To call the callBapi_Create_Order of Custom Controller 2) To call callBapi_Commit()
No issues with connecting to R/3 i.e JCO Destinations etc., are good since the Retrieval BAPI works with no problems.
Am I missing something here ? Any help is appreciated....

Answer 1

Thank You. Here is my code. I am only showing the code that I have changed:
View Controller Action Method:
public void onActionCreateOrder
    //@@begin onActionCreateOrder(ServerEvent)
    wdThis.wdGetCreteOrderCustControllerController().callBapi_Zpm_Create_Order();
    wdThis.wdGetCreteOrderCustControllerController().callBapi_commit();
    //@@end
The Custom Controller code:
  public void wdDoInit()  {
  Zpm_Create_Order_Input input = new   Zpm_Create_Order_Input();
  Zpm_Vmo_Hdr ordHdr = new Zpm_Vmo_Hdr();
  input.setOrder_Header(ordHdr);
  wdContext.nodeZpm_Create_Order_Input().bind(input);
Bapi_Transaction_Commit_Input
  Bapi_Transaction_Commit_Input inputCommit =
  new Bapi_Transaction_Commit_Input();
  wdContext.nodeBapi_Transaction_Commit_Input().bind(inputCommit);
  public void callBapi_Zpm_Create_Order( )  {
     IWDMessageManager manager = wdComponentAPI.getMessageManager();
     try{
       wdContext.currentZpm_Create_Order_InputElement().modelObject().execute();
       wdContext.nodeOrder_Header().invalidate();
     }catch(Exception e){
          manager.reportException(e.getMessage(),false);
  public void callBapi_commit( )
     IWDMessageManager manager = wdComponentAPI.getMessageManager();
     try{
       wdContext.currentBapi_Transaction_Commit_InputElement().modelObject().execute();
     }catch(Exception e){
          manager.reportException(e.getMessage(),false);
    //@@end
