RFC model values are not shown in table

Question

Hi there,
I can't gather the values from the RFC FM in my table, while this has been done exactly the same way as other tables which do get values... Any reason for this?
I have 2 DC's:
-data DC which acts as a container for the RFC-imported datamodels
-bupa DC in which the implementation is done
Custom Controller CuCoMain (from bupa DC):
Context:
OutputRelContacts (model node bound to model BuPaRelationsModel.__Crm_Bb_Bupa_Rels_Output)
cardinality: 0...n; selection: 0...1
> Rel_Contacts_Result (node of OutputRelContacts)
=> bound to BuPaRelationsModel.__Crm_Bb_Bp_Rel_Res_Ds
cardinality: 0..n; selection: 0...1
There is no context input necessary since 'related contacts' is dependent of the bpnr which I pass as parameter (see below).
Implementation in CuCoMain
public void TriggerAccConSearch( java.lang.String Mode, java.lang.String BuPaNr )
    //@@begin TriggerAccConSearch()
     //also see comments in TriggerBuPaSearch
     accContactsInput = new __Cernum__Crm_Bb_Bupa_Rels_Input();
     accContactsInput.setRel_Mode(Mode);
     accContactsInput.setBp_Number(BuPaNr);
     try{
          accContactsInput.execute();
          wdContext.nodeOutputRelContacts().invalidate();
          accContactsOutput = accContactsInput.getOutput();
          this.wdThis.wdGetContext().nodeOutputRelContacts().bind(accContactsOutput);
     catch(Exception e){
          msgMngr.reportException(e.getMessage(),true);
    //@@end
Context in view
Context node OutputAccContacts (bound to CuCoMain.OutputRelContacts.Rel_Contacts_Result)
cardinality: 0...n; selection: 0...1
Implementation to trigger TriggerAccConSearch:
String SelectedBuPaNr = this.wdThis.wdGetContext().nodeVOutputDetails().currentVOutputDetailsElement().getBpnumber();
     String RelMode = "C";
     this.wdThis.wdGetCuCoMainController().TriggerAccConSearch(RelMode, SelectedBuPaNr);
RelMode & SelectedBuPaNr are filled with values.
So what did I do wrong...? I'm out of inspiration; I've reimported the model, rebuilt the entire application, redone the context, redone the implementation but up until now nothing worked.
Any help is greatly appreciated

Hi there,
Yes, as stated earlier, my RFC is being called by the application and the parameters are correct (input & output). Somehow, these values just don't get transferred to the node.
Also, you can try the following piece of code before the RFC call at the Dynpro end :
IWDMessageManager manager = wdComponentAPI.getMessageManager();
try{
wdContext.current<RFC_Name>_InputElement().modelObject().execute();
wdContext.node<Output_Node_Name>().invalidate();
} catch(WDDynamicRFCExecuteException ce) {
manager.reportException(ce.getMessage(), false);
I don't think that will help in my situation. In my situation there are 3 tables which have to be filled by the nodes.
These 3 tables are all based on the same RFC (with different input parameters). The weird thing is that one of these tables works perfectly and the others just don't work. Even weirder is that all the RFC-uses are implemented the same. (See below)
The working RFC call (table is populated):
public void TriggerAccRelSearch( java.lang.String BuPaNr, java.lang.String Mode )
    //@@begin TriggerAccRelSearch()
     //also see comments in TriggerBuPaSearch
     accRelsInput = new __Crm_Bb_Bupa_Rels_Input();
     accRelsInput.setRel_Mode(Mode);
     accRelsInput.setBp_Number(BuPaNr);
     try{
          wdContext.nodeOutputRelationships().invalidate();
          accRelsInput.execute();
          accRelsOutput = accRelsInput.getOutput();
          //wdComponentAPI.getMessageManager().reportWarning("TriggerAccRelSearch Result of RFC START" + accRelsOutput.getRel_Result().listIterator()..toString() + "TriggerAccRelSearch Result of RFC START");
          //wdComponentAPI.getMessageManager().reportWarning("First line: " + accRelsOutput.getRel_Result().get(0).toString());
          //currentRel_ResultElement().getRelationship().toString());
          this.wdThis.wdGetContext().nodeOutputRelationships().bind(accRelsOutput);
          wdComponentAPI.getMessageManager().reportSuccess("test accrelsearch: " + wdContext.nodeOutputRelationships().nodeRel_Result().currentRel_ResultElement().getAttributeAsText("Relationship").toString());
     catch(Exception e){
           msgMngr.reportException(e.getMessage(),true);
     finally{
          DynamicRFCModel modelinst;
          modelinst = (DynamicRFCModel) WDModelFactory.getModelInstance(BuPaRelationsModel.class);
          modelinst.disconnectIfAlive();     
    //@@end
The non-working RFC-calls (tables are NOT populated):
public void TriggerAccReltdEmpSearch( java.lang.String Mode, java.lang.String BuPaNr )
    //@@begin TriggerAccReltdEmpSearch()
     accReltdEmplInput = new __Crm_Bb_Bupa_Rels_Input();
     //accReltdEmplOutput = new __Crm_Bb_Bupa_Rels_Output();
     accReltdEmplInput.setRel_Mode(Mode);
     accReltdEmplInput.setBp_Number(BuPaNr);
     try{
          wdContext.nodeOutputReltdEmp().invalidate();
          accReltdEmplInput.execute();
          accReltdEmplOutput = accReltdEmplInput.getOutput();
          this.wdThis.wdGetContext().nodeOutputReltdEmp().bind(accReltdEmplOutput);
          //wdComponentAPI.getMessageManager().reportSuccess("test accReltEmp: " + wdContext.nodeOutputReltdEmp().nodeReltd_Emp_Result().currentReltd_Emp_ResultElement().getAttributeAsText("Relationship").toString());          
     catch(Exception e){
          msgMngr.reportException(e.getMessage(), true);
          msgMngr.reportSuccess("error: " + e.getCause());
     finally{
          DynamicRFCModel modelinst;
          modelinst = (DynamicRFCModel) WDModelFactory.getModelInstance(BuPaRelationsModel.class);
          modelinst.disconnectIfAlive();          
    //@@end
and:
public void TriggerAccConSearch( java.lang.String Mode, java.lang.String BuPaNr )
    //@@begin TriggerAccConSearch()
     //also see comments in TriggerBuPaSearch
     accContactsInput = new __Crm_Bb_Bupa_Rels_Input();
     accContactsInput.setRel_Mode(Mode);
     accContactsInput.setBp_Number(BuPaNr);
     try{
          wdContext.nodeOutputRelContacts().invalidate();
          accContactsInput.execute();
          accContactsOutput = accContactsInput.getOutput();
          wdComponentAPI.getMessageManager().reportWarning("TriggerAccConSearch Result of RFC START" + accContactsOutput.getRel_Result().toString() + "TriggerAccConSearch Result of RFC START");
          this.wdThis.wdGetContext().nodeOutputRelContacts().bind(accContactsOutput);
     catch(Exception e){
          msgMngr.reportException(e.getMessage(),true);
     finally{
          DynamicRFCModel modelinst;
          modelinst = (DynamicRFCModel) WDModelFactory.getModelInstance(BuPaRelationsModel.class);
          modelinst.disconnectIfAlive();     
    //@@end
Parameter definition:
__Crm_Bb_Bupa_Rels_Input accRelsInput;
__Crm_Bb_Bupa_Rels_Output accRelsOutput;
__Crm_Bb_Bupa_Rels_Input accReltdEmplInput;
__Crm_Bb_Bupa_Rels_Output accReltdEmplOutput;
__Crm_Bb_Bupa_Rels_Input accContactsInput;
__Crm_Bb_Bupa_Rels_Output accContactsOutput;
The table dataSources have all been bound to the context properly, as well as the table columns. Also, in the backend the correct values have been passed and retrieved.
