Hello,

I have created a Simulink model that allow the user to simulate some Constant (True = not OK / False = OK), and spread the information to upper block.

To do that i have a function block (Function Matlab) that change the color of the upper block (Function A block) according to the information he receive :

function y = fcn(u)
coder.extrinsic('set_param','get_param','gcs');
parent = get_param(gcs,'parent');
y = u;
if u == 3
    set_param(parent,'BackgroundColor','red');
elseif u == 2
    set_param(parent,'BackgroundColor','orange');
elseif u == 1
    set_param(parent,'BackgroundColor','gray');
else
    set_param(parent,'BackgroundColor','green');
end

So if he receive 3 the Block "Function A" goes red, 2 => Orange, 1=> Gray and if all is good => Green.

In my 2017b Matlab all is working well, but when i test my model in 2019b Matlab the uppers Block colors don't change as if the Function Block don't work in 2019b.

Do you know what changed between versions ?

Thanks for helping in advance.

PS : I attached the example model : Simulate.slx
