* Fix multiple file options showing up (#987)
This change ensures that the file options composite widget is
hidden if and only if none of its components is in focus. This
is achieved by having a variable keep track of the state of
the composite widget (in focus / not in focus).
* Fix#987
Modified fix for #987 according to the requested changes.
Moved isFocused to the components state and created a method
for hadling the function calls executed in onBlur.
* Fix#987 - final touches
Renamed method blurComponent to onBlurComponent. Moved duplicated
code from onFocus callback to a new method called onFocusComponent.
