Empty view after pop -> rotation -> back to view

[marcelglaeser]

Hello to all,
i hope that i can explain my problem.

I see the ListView plus the Accordion and all works fine, but if a go to the next page (Navigation pop), rotate the iPhone and go back to the ListView with the Accordion elements, the ListView is empty.

When i don't use the Accordion, i can see all ListView entities.

How can i fixed?

Thanks for support
Marcel
