No Viewclass Error in 800xA when page up or page down
I faced one problem abuot the "No Viewclass" Error in 800xA when page up or page down as attached. the graphic can be changed by click the guide button. But when I use the page down or page up to choose the next page or previous page, it shows No Viewclass.
The grahics are created in function structure, the main page is level 2, and 5 object in level 3. please see as attached.
Thank you in advance!
