XTP 15.02 with Visual Studio 2010 on W7

I have a reproducible bug when calling

CXTPDockingPane* ppane = m_paneManager.FindPane(ID);
if (ppane) {
   if (ppane->IsClosed()) {
       ppane->SetEnabled(xtpPaneEnabled);
       m_paneManager.ShowPane(ppane);
   }
   else {
       ppane->SetEnabled(xtpPaneDisabled);
       m_paneManager.ClosePane(ppane);
   }
}

XTP crashes in NotifyAction()

void CXTPDockingPaneAutoHidePanel::CloseActiveWindow(BOOL bDelayed)
{
   if (!m_bCloseActiveWindow)
       return;

   if (m_pActiveWnd)
   {
       if (m_pActiveWnd->m_pPane)
       {

// BUG m_pActiveWnd->m_pPane->GetSelected() is NULL

           if (GetDockingPaneManager()->NotifyAction(xtpPaneActionCollapsing, m_pActiveWnd->m_pPane->GetSelected()))
               return;

           GetDockingPaneManager()->NotifyAction(xtpPaneActionCollapsed,
               m_pActiveWnd->m_pPane->GetSelected());
       }

If the pane I'm trying to close is an autohide panel (IsHidden() returns true) and the pane is currently visible (opened but in auto-hide mode).

Thanks, fixed.

btw, maybe you need xtpPaneEnableActions instead of xtpPaneDisabled to disable client part only but not all actions...

I, Oleg

thanks. Can I make a work-around in your code so it works here till your next update?

Thanks. I will look into this.

My code just wants to implement a method for the user to open/close panes via the keyboard. If a pane is a auto-hide pane I want to close it when it is not visible (collapsed) and hide it when it is visible.
Closing/Showing normal panes that way works, but not for auto-hide panes.

Hi,

Problem can be reproduced only if you set xtpPaneDisabled - without it it won't crush. So most easy workaround here to not set xtpPaneDisabled before Close.
