Docking panes and CXTOutBarCtrl

I am trying to put an CXTOutBarCtrl on a CXTPDockingPane without any luck. The CXTOutBarCtrl appears on the pane but the folders in the CXTOutBarCtrl is not scrolling. Has anyone got this working? Here is the code I am using:

CXTOutBarCtrl* out = new CXTOutBarCtrl;
out->Create(WS_VISIBLE | WS_CHILD, CRect(0, 0, 0, 0), this, 1);
out->AddFolder("Folder1", NULL);
out->AddFolder("Folder2", NULL);
out->AddFolder("Folder3", NULL);
out->SetOwner(this);
m_Panes.InstallDockingPanes(this);
CXTPDockingPane* pane = m_Panes.CreatePane(1, CRect(0, 0, 210, 140), dockLeftOf);
pane->Attach(out);
