Topic: Reproducible crash - selecting an autohidden pane

We use XTP 10.1; in the "PaneActions" sample try to close all panes (from GUI), then call a method like this:

void CMainFrame::OnDoCrashAction()
{
    CXTPDockingPane* pPaneResourceView = m_paneManager.FindPane(IDR_PANE_RESOURCEVIEW);
    if (pPaneResourceView)
    {
        m_paneManager.ShowPane(pPaneResourceView);
        m_paneManager.ToggleAutoHide(pPaneResourceView);
        pPaneResourceView->Select();
    }
}

With this code I'd like to re-open an autohidden pane and select it. However, first I get an assert complaining about atlmfc\include\afxwin2.inl, line 150. If I click ignore, then it's OK until I hover the mouse above the newly opened ResourceView. By this hovering I get a crash: an access violation inside CXTPDockingPaneAutoHidePanel::OnMouseHover(). The value of m_pActiveWnd->m_pPane is 0xfeeefeee.

Do you know any workaround for this?
Any fixes available in newer versions?

Thank you, in advance!

Hi,

This code works for me:

CXTPDockingPane* pPaneResourceView = m_paneManager.FindPane(IDR_PANE_RESOURCEVIEW);
    if (pPaneResourceView)
    {
  m_paneManager.ShowPane(pPaneResourceView);
  pPaneResourceView->Hide();
  RecalcLayout();
        pPaneResourceView->Select();
    }

Indeed, RecalcLayout() was the key to solution. Excellent, thank you.
