Android Question CLV item with listview. scroll event always taken by the CLV

Hi,
I know it's not ideal and and I will probably change it but at the moment I have a CLV where one of the item contains a listview filled with some items. the issue I am facing is that it seems that the scroll event is always received by the CLV even if I try to scroll the list from inside the listview.
is that a bug or a desidered behavior?
thanks
