set the list to be not focusable. doing this kind of thing with focus as a
result of actions on 1 widget to set focus on another is ALWAYS bound to have
conflicts. your alternative is to set the focus in a timer (ie wait 0.2 sec
then focus other button hoping that list has finished its human interactions by
then). you are at the mercy of policies that are flexible and may change from
desktop to touchscreen to something else.
