WebDynpro Table Element to BAPI.

Question

Dear ALL
I have a Table filled with data in Java WebDynpro. I need to pass the data to BAPI.
Table is bind to a Value Node Education, which is linked with a strucutre of BAPI.
Now how I would passs the values of table to BAPI and where I will pass this value weather in a view or custome controller.
BAPI has following paramters.
Import     EDUCATION_IMP     TYPE     ZONLINE_EDU
Export    EDUCATION_EXP     TYPE     ZONLINE_EDU
Table      EDUCATION_TAB     LIKE     ZONLINE_EDU
In the view I also tried to pass the value by hard codeing but getting java null exception.
   wdContext.currentEducation_ImpElement().setMajor("Physics");
   wdContext.currentEducation_ImpElement().setGpa("2.3");
   wdContext.currentEducation_ImpElement().setPassyear("2008");
   wdContext.currentEducation_ImpElement().setInstitute("PAF");
   In view I am calling an action.
  public void onActionInsertApplication(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionInsertApplication(ServerEvent)
    wdThis.wdGetInsertApplicationCustController().executeZONLINE_APP();
    //@@end
And custome controller has following code.
public void executeZONLINE_APP( )
    //@@begin executeZONLINE_APP()
    try
         wdContext.currentZONLINE_APPElement().modelObject().execute();
         wdContext.currentZRFC_ONLINE_EDUElement().modelObject().execute();
    catch ( Exception ex)
         ex.printStackTrace();
    wdContext.nodeOutput().invalidate();
    //@@end

Answer 1

getting java null exception on
wdContext.currentEducation_ImpElement().setMajor("Physics");
because the node Education_Imp is not existing during runtime. check the cardinality of that node which is set to 0..n
sol: you need to create the element before you are setting/accessing the element.
IPrivate<Comp_Name>.IEducation_ImpElement newelm;
newelem = wdContext.createEducation_ImpElement();
wdContext.nodeEducation_Imp().bind( newelm);
you need to create element for each record of EDUCATION_IMP TYPE ZONLINE_EDU Type.
same code will do and you can assign the values too.
you can do it in view controller itself
Now,  call component controllers' method.
try
wdContext.currentZRFC_ONLINE_EDUElement().modelObject().execute();
catch ( Exception ex)
ex.printStackTrace();
wdContext.nodeEDUCATION_EXP().invalidate();
