Docking pane crash with MFC ...

Hi,

  The problem occures when I try to create a docking pane and specify another (hidden one) as its neigbour!

Here is the code:

  CXTPDockingPane* pPaneClassView = m_paneManager.CreatePane(IDR_PANE_CLASSVIEW,  &nbs p; CRect(0, 0,200, 120), dockLeftOf, NULL);
 if (pPaneClassView) {
    m_paneManager.HidePane(pPaneClassView);
 }

 CXTPDockingPane* pPaneInfoView = m_paneManager.CreatePane(IDR_PANE_INFOVIEW, CRect(0, 0,200, 120), dockLeftOf, pPaneClassView); // this crashes the application !!!!
  if (pPaneInfoView ) {
   m_paneManager.AttachPane(pPaneInfoView , pPaneClassView );   
  }  

Can this be fixed somehow?

Thanks

Yes, I know that

The problem is that I need to use the docking pane the way I've described !

Due to some application requirements I need to attach docking panes at runtime to a hidden one.

A new docking pane can be attached at any time during the application lifetime.

Oleg,

 I tried to create it the way you said, but the result is still not the one expected! If I set the neighbour to NULL and then call 'AttachPane' the two panes are not being attached ! Instead they seem to be just docked at one and the same side of the frame window.

This behaviour confuses me. Since I have the pane created, why should I care whether it is visible or not? As a developper I don't need to know whether a particular window is visible in order to use it's methods (like SetWindowText for example)!

  Now is this a bug or the whole toolkit is based on this strange idea?

  My employer requires this feature but I can't think of a solution !!!

 So can this be fixed and when?

Oleg,

 here is a test project. Try executing the commands in the "My Actions" menu. The problem occurs when creating the third docking pane ! The example specifies a NULL neighbour to all the docking panes created. If I try to set the first docking pane as the neighbour of all the others the application asserts. 

Thanks for your help
