Hmm, currently I'm unable to reproduce it in a simple project. It still happens in my app.
I fill two CustomListViews with entries. Both of them on a AHViewPager Page.
When the first LisView is filled, I jump to a specific entry of the CustomListView with JumpToItem.
The app crashes when all refreshes to the screen are done (seems so because the complete code has run).
If I remove the two DoEvents from JumpToItem the exception does not occur. If I fill both CustomListViews without jumping to the position in the first List everything is fine, too. After both listviews are initialized I can refresh the list entries and jump to an item, too.
I currently have no idea how to reproduce it. Fact is that in 5.20 all worked well. In 5.5 Beta I get the crash. Tried it on a Nexus 5 with Android 6 and a Nexus 7 with 5.1.1.
