[sMystero]

Hi all.
Another problem on my plugin.
Why do I receive on xbmc.log this message: CGUIMediaWindow::GetDirectory(plugin://plugin.vid eo.smytvshow/?action=list_null&source=main_menu&source_type=M&target=main_menu&target_type=M) failed
It happens when I terminate the execution of my video plugin without making any call to endOfDirectory.
How can this be achieved?
For example when the user click on a specific item in my previously loaded list, I would like to give him a dialog and stopping execution.
Pls help. I'm stucked.
