Bug 107827 [build path] Edit Library dialog error status stays after wrong selection
I20050818-0800 Steps to reproduce: - Create a new user library and put it on the build path as container - Make sure this is the only user library - Invoke "Configure..." from the Package Explorer context menu on the container - Edit Library dialog appears - Try to unselect the user library -> Error status appears, but library is still selected -> Error status only disappears if the dialog is cancelled and redisplayed or the "User Libraries..." button is pressed
