Weird Problem in WebDynpro

Question

Hi gurus!!
I created a WD project:
- created a model with reference to a ZBAPI
- created a Component
- created a Custom Controller with 2 nodes: one to the INPUT class of the model, and the other to the OUTPUT class of the model
- created a View Main
- created a View Result
- bind the context of view Main to the INPUT node of the custom controller
- bind the context of view Result to the OUTPUT node of the custom controller
- At the end I have 2 views of the same component related to the same custom controller, and this custom controller related to both the INPUT and OUTPUT classes of the main model
- added the fields to the corresponding views
- on the view Main:
  public void wdDoInit()
    //@@begin wdDoInit()
    Bapi_header_getdetail = new Zbapi_Wty_Header_Getdetail_Input();
    wdContext.nodeInput().bind(Bapi_header_getdetail);
    //@@end
- added a button to the view Main, and on the action:
  public void onActionBuscar(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionBuscar(ServerEvent)
   try {
   Bapi_header_getdetail.execute();
   wdThis.wdFirePlugToResult();
   } catch (Exception ex) {
      ex.printStackTrace();
    //@@end
- added a viewset to the Main window, and embedded both views to the viewset.
- created the inbound and outbound plugs to the corresponding views
- created a project, deploy and run
I execute the app, push the button, but no values are displayed on the results view.
I verified the bapi, it's getting executed and is returning the values correctly, but still they're not getting displayed. I made sure of that, because I have the bapi create a text file on the server with the values it found, so I know for sure it's getting executed correctly.
I wonder if there's some step I might have missed.
The BAPI has 2 import parameters, and a Z structure as an export parameter.
Does anyone have a clue what might be the error!?
Thanx

Hi Jesus,
I think BAPI is not executing properly. Check the size of Output Node.
Try this.
public void onActionBuscar(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
//@@begin onActionBuscar(ServerEvent)
try {
wdContext.currentZbapi_Wty_Header_Getdetail_InputElement().modelObject().execute();
wdContext.nodeOutput().invalidate();
wdComponentAPI.getMessageManager().reportSuccess("Output Node Size : "+wdContext. nodeOutput().size());
wdThis.wdFirePlugToResult();
} catch (Exception ex) {
ex.printStackTrace();
//@@end
populating a table with bapi
