Waveform viewer blank in batch mode simulation

I'am simulating a very simple example:

xvhdl mux_vunit_tb.vhd
xelab -debug all mux_tb -s mux_tb --runall

It runs fine, I have the report and no errors. But when I open mux_tb.wdb with the "Open static simulation" tool the waveform viewer is blank.

Any idea?

 

 

--! Standard library.
library ieee;
--! Logic elements.
use ieee.std_logic_1164.all;
--! Arithmetic functions.
use ieee.numeric_std.all;
--
library std;
use std.textio.all;

entity mux_tb is
end;

architecture bench of mux_tb is
-- clock period
constant clk_period : time := 5 ns;
-- Signal ports
signal clk: std_logic := '0';
begin

main : process
begin
wait for 10*clk_period;

report("info 0");

wait for 10*clk_period;

wait for 10*clk_period;

report("info 1");

wait for 10*clk_period;

std.env.stop;
end process;

clk_process :process
begin
clk <= '1';
wait for clk_period/2;
clk <= '0';
wait for clk_period/2;
end process;

end;

Maybe adding "current_fileset" tcl command works.
current_fileset
open_wave_database mux_tb.wdb

Feel free to accept as solution if it solves your issue.
