CL_GUI_CALENDAR show only year 2016

Hi all

How can I force the CL_GUI_CALENDAR to show only the year 2016.

I tried with

  c_gobj_calendar = new cl_gui_calendar( parent = c_gobj_container view_style = lf_style                                            year_begin = conv i( 2016 ) year_end = conv i( 2016 ) ).

But it shows me the year 2015 too.

Why?

Thanks
