ADF Faces and multiframe window for master/detail view

Question

Hi,
I have a web page divide into 2 frames : frame1, the master view and frame2 the detail view.
When I load the whole web page, the master frame print all the paginated list. Each row has a "show more" button. When I click one, the corresponding detail view is displayed in the detail view (frame2). And, when I clicked again the "show more" button, the paginated list (present in the master view) is displayed in the detail view !!! WHY ??
When I click a third time on the "show more" button, the detail view display the corresponding detail information (work well like first click)....and alternatively clicking on the "show more" button, this problems occurs.
Where does this problem come from ?
The ADF Faces code shown in the master view (targetFrame attribute means to display on the detail view when show more button is clicked).

Answer 1

Yes I put a targetFrame (I forgot to restablish it).
Code of the backing bean (to show building list) :
public List getBuildingsList() throws Exception {
          System.out.println("getBuildings");          
          CLPNetworkInstanceAPI netAPI = CLPNetworkInstanceAPI.getNetworkInstanceAPI();
          buildingsList.clear();
try {
     CTResource resources[] = netAPI.fetchAllResourcesByType("CLPRMBuilding");      
               for (int i=0; i<resources.length;i++)
                    buildingsList.add(resources);
          } catch (CTConnectionException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          } catch (CTUnsupportedTypeException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          return buildingsList;
and the backing bean to show building detail :
public String showBuilding() {
          FacesContext context = FacesContext.getCurrentInstance();
          CLPRMBuilding building = (CLPRMBuilding)
     context.getApplication().getVariableResolver().resolveVariable(context, "building");
     if (building == null)
     return "error";
     AdfFacesContext afContext = AdfFacesContext.getCurrentInstance();
     afContext.getProcessScope().put("buildingDetail", building);
     return "showBuilding";
