source file in which a dialog with tab pages is created

When creating a UNO dialog in Java (using Libreoffice SDK 4.2.7.2 coded using the Netbeans Openoffice plugin 4.0.6) adding tab pages to a dialog does not work. 

I am adding tab pages by creating a UnoControlTabPageContainerModel, querying its interface and subsequently adding individual tab pages to it by using the function createTabPage(). However, in Libreoffice it merely shows a dialog window without tab pages. 

However, the same code reportedly works in Openoffice (see user Hanya in https://forum.openoffice.org/en/forum/viewtopic.php?f=44&t=74391&p=336538#p336538) and produces a functional dialog with tab pages.


The important part of the code (full code is attached below):

Object oDialogProvider =m_xMCF.createInstanceWithContext("com.sun.star.awt.DialogProvider", m_xContext);
XDialogProvider xDialogProvider = UnoRuntime.queryInterface(XDialogProvider.class, oDialogProvider);
XDialog xDialog = xDialogProvider.createDialog("vnd.sun.star.script:Standard.Dialog1?location=application");
     
      if (xDialog == null) return;
      XControlModel xDialogModel = UnoRuntime.queryInterface(XControl.class, xDialog).getModel();
      XMultiServiceFactory xMsf = UnoRuntime.queryInterface(XMultiServiceFactory.class, xDialogModel);
     
         XNameContainer xNameContainer = UnoRuntime.queryInterface(XNameContainer.class, xDialogModel);
         
         Object tabPagesModel = xMsf.createInstance("com.sun.star.awt.tab.UnoControlTabPageContainerModel");
         xNameContainer.insertByName("tab", tabPagesModel);
         XPropertySet xPropSet = UnoRuntime.queryInterface(XPropertySet.class, tabPagesModel);
         xPropSet.setPropertyValue("Width", 100);
         xPropSet.setPropertyValue("Height", 100);
         
         XTabPageContainerModel xTabPagesModel = UnoRuntime.queryInterface(XTabPageContainerModel.class, tabPagesModel);
         
         XTabPageModel xTabPageModel1 = xTabPagesModel.createTabPage((short) 1);
         xTabPageModel1.setTitle("Page 1");
         xTabPagesModel.insertByIndex(0, xTabPageModel1);
         XTabPageModel xTabPageModel2 = xTabPagesModel.createTabPage((short) 2);
         xTabPageModel2.setTitle("Page 2");
         xTabPagesModel.insertByIndex(1, xTabPageModel2);
