RFC function : passing a table as input

Question

Hi,
I have no trouble passing input values to an RFC model in web dynpro, but I have difficulties to pass an input table.
By default, the input "it_table" node of the model I use, is defined like this : card 0..n, selec 0..1 Singleton True.
Do I have to change something?
Then, what is the correct code for creating the node (because card is 0..n) and then add items (for each line of my table)?
For the moment, I get this error : value node is created without a reference.
Thanks

Answer 1

I finally managed to get it work.
Here is the COMPLETE solution.
Note that in my solution, it was easier for me to put data in a value Node FIRST and THEN to copy it to the model Node.
--> In the RFC function, declare the table "TYPE TLINE_T", and not "LIKE TLINE".
GestionAvisComp - Context
- Z2_I_Gestion_Simplifiee_Avis_Input (Model Node, card 0..1, sel 0..1, singleton true)
         + It_Ajout_Texte_Avis (card 0..n, sel 0..1, singleton true) Class Tline
            - Tdformat
            - Tdline
         - Qmart
- It_Texte_Avis (Value node, card 0..n, sel 0..1, singleton true)
  public void wdDoInit()
    //@@begin wdDoInit()
     //$$begin Service Controller(1353609186)
     Z2_I_Gestion_Simplifiee_Avis_Input input = new Z2_I_Gestion_Simplifiee_Avis_Input();
     wdContext.nodeZ2_I_Gestion_Simplifiee_Avis_Input().bind(input);
     //$$end
    //@@end
WhateverView
public void onActionSauvegarderAvis(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
     // Add two elements to the value node
     IIt_Texte_Avis_InputElement firstTexte_AvisEl = wdContext.nodeIt_Texte_Avis_Input().createIt_Texte_Avis_InputElement();
     IIt_Texte_Avis_InputElement secondTexte_AvisEl = wdContext.nodeIt_Texte_Avis_Input().createIt_Texte_Avis_InputElement();
     firstTexte_AvisEl.setTdformat("/*");
     firstTexte_AvisEl.setTdline("Line 1");
     secondTexte_AvisEl.setTdformat("/*");
     secondTexte_AvisEl.setTdline("Line 2");
     wdContext.nodeIt_Texte_Avis_Input().addElement(firstTexte_AvisEl);
     wdContext.nodeIt_Texte_Avis_Input().addElement(secondTexte_AvisEl);
     // Moving the elements of the value node into the model node
     int size = wdContext.nodeIt_Texte_Avis_Input().size();
     for (int i = 0; i < size; i++) {
          wdContext.nodeIt_Texte_Avis_Input().setLeadSelection(i);
          Tline x = new Tline();
          x.setTdformat(wdContext.currentIt_Texte_Avis_InputElement().getTdformat());
          x.setTdline(wdContext.currentIt_Texte_Avis_InputElement().getTdline());
          wdContext.currentZ2_I_Gestion_Simplifiee_Avis_InputElement().modelObject().addIt_Ajout_Texte_Avis(x);
     wdContext.currentZ2_I_Gestion_Simplifiee_Avis_InputElement().setQmart("ZE");
     // Execute the RFC model
     // Clear the Value Node
     while ( wdContext.nodeIt_Texte_Avis_Input().size() > 0 )
               wdContext.nodeIt_Texte_Avis_Input().removeElement(
                    wdContext.nodeIt_Texte_Avis_Input().getElementAt(0)
     // Clear the Model Node          
          if (wdContext.currentZ2_I_Gestion_Simplifiee_Avis_InputElement().modelObject().getIt_Ajout_Texte_Avis() != null) {
          while(wdContext.currentZ2_I_Gestion_Simplifiee_Avis_InputElement().modelObject().getIt_Ajout_Texte_Avis().size() > 0)
               wdContext.currentZ2_I_Gestion_Simplifiee_Avis_InputElement().modelObject().getIt_Ajout_Texte_Avis().remove(0)
