Hello!
I’ve found trouble with scrolling at
Android
devices ( with different hardware versions: 4.0.4, 4.2.2, 5.1 ).
First view has NativeButton with some custom ClickListener and TextField with ShortcutListener.
TextField and NativeButton are used for searching, i.e. you can write something into textfield and press button or use “enter” shortcut. ( see attachment )
Both listeners have the same code inside action handlers:
Button.ClickListener newSearchListener = createNewSearchListener();
newSearchListener.buttonClick(null);
After view changing I have second view with table with big count of elements inside it.
So if you use TextField shortcut everything will be ok.
But if you write something into the textfield, hide a keyboard on device and press button, view will be changed and you couldn’t use scrolling.
I have a suspicion that the problem is calling buttonClick inside buttonClick 
P.S. Sorry for bad english
upd: We use vaadin touchkit cval 2.1.5
