import XML in Commandbar designer

Hi
I have a created a commandbars XML file from the sample "DesignerSample" with this part of code:

    CXTPCommandBars* pCommandBars = GetCommandBars();
    CXTPImageManager* pImageManager = pCommandBars->GetImageManager();

    XTP_COMMANDBARS_PROPEXCHANGE_PARAM param;
    param.bSerializeControls = TRUE;
    param.bSaveOnlyCustomized = FALSE;
    param.bSerializeDesignerControls = TRUE;

    // Serialize to XML
    CXTPPropExchangeXMLNode px(FALSE, 0, _T("DesignerFile"));
    pCommandBars->DoPropExchange(&px, &param);

    // Icons
    CXTPPropExchangeSection secImages(px.GetSection(_T("Images")));
    pImageManager->DoPropExchange(&secImages);

    // Accelerators:
    CXTPPropExchangeSection secShortcuts(px.GetSection(_T("Shortcuts")));
    XTPShortcutManager()->DoPropExchange(&secShortcuts, this);

    px.SaveToFile(_T("test.xml"));

When i import the XML in the designer the "controls tab" is empty.
I have analysed the XML file. In my file the sections "Shortcuts", "Options", "ResourceManager" doesn't exist. Is this the problem,

because i don't need this sections.

I need to get the contols tab to work, because i want to edit menu entries. Toolbar entries editing does work.

thanks

P.s.: For this peace of code and the loading of this designed bars, i have needed 1 day of work (to find information in forum and in the source code).  With a simple example this should be done in 5 minutes.
