I'm having trouble moving views between Docking panes and childframes. I have the following code that moves the active view between a Pane and a CChildFrame.

CView *activeView = (CView*) GetFocus();

if (pane->IsClosed() && !pane->IsFloating())
{
  // View is in childframe as pane is not visible (closed and not floating)
  pane->Attach(activeView);
  m_paneManager.ShowPane(pane);

CChildFrame *activeChild = (CChildFrame*) GetActiveFrame();
activeChild->SendMessage(WM_CLOSE);

  pane->SetFocus();
  *bInFrame = false;
}
else
{
  // Pane is visible, so move to a child window
  CChildFrame *child = createCircaView(activeView->GetRuntimeClass());

  // Move the view onto the new childframe and move the new (unrequired) view
  // into the pane that is going to be destroyed.
  activeView->SetParent(child);
  child->SetActiveView(activeView);

// Now activate and update the childframe
m_MTIClientWnd.Refresh();

  // Close the relevant pane
  m_paneManager.ClosePane(pane);
  *bInFrame = true;
}

This code seems to work in so much as it moves the view correctly between a pane and a CChildFrame, but the problem is later in my code, if the view is in a CChildFrame, then when I ask the view for ->GetParent(), I expect to get a pointer to a CChildFrame, but instead, I get a pointer to CXTPDockingPaneManager. If I ask for ->GetParentFrame(), I get the CMainFrame!. How do I get the CChildFrame parent of my View? Perhaps it is not getting set using the SetParent() call above?
