Adding a another View/Frame to a document

[zspirit]

My document has multiple views. I am adding another view whose frame class is different and it initial size comes up to zero (just the title bar of the window shows up).

        CChildFrame* pNewFrame = (CChildFrame*) theApp.m_pMyDocTemplate->CreateNewFrame( pDoc, pFrame );

        // create new view
        if (pNewFrame != NULL )
            pNewFrame->InitialUpdateFrame(pDoc, TRUE);

I have other views added too and they work fine. I know the difference is that these other views have the same CFrameWnd in the CMultiDocTemplate but this new view has a difference frame class

m_pTestDocTemplate = new CMultiDocTemplate(
        IDR_MAINFRAME, 
        RUNTIME_CLASS(CTestDoc),
        RUNTIME_CLASS(CChildFrame), 
        RUNTIME_CLASS(CTestView));
    AddDocTemplate(m_pTestDocTemplate);

m_pTest2DocTemplate = new CMultiDocTemplate(
        IDR_MAINFRAME, 
        RUNTIME_CLASS(CTestDoc),
        RUNTIME_CLASS(CChildFrame), 
        RUNTIME_CLASS(CTest2View));
    AddDocTemplate(m_pTest2DocTemplate);

m_pTest3DocTemplate = new CMultiDocTemplate(
        IDR_MAINFRAME, 
        RUNTIME_CLASS(CTestDoc),
        RUNTIME_CLASS(CChildCustomFrame), // custom MDI child frame
        RUNTIME_CLASS(CTest3View));
    AddDocTemplate(m_pTestDocTemplate);

As you can see from the definitions, when I add m_pTest2DocTemplate it works fine because the CChildFrame is the same but adding m_pTest3DocTemplate starts the new view in zero size perhaps because of different frame class?

What is the strategy to add the view if their is a different frame class involved as well? The custom frame class that I am using controls the sizing requirements of the view in my case.
