initial() does not seem to work

[gunnar.andersson]

Consider the following model:

class InitialBug

Real x(start = 1.5);
discrete Real y;

equation

when {initial(), sample(0.2, 0.5)} then

y = x;

end when;
der(x) = -x;

end InitialBug;

When simulated and plotted using

simulate(InitialBug)
plot({x, y})

one sees that y(t) is 0 for t in [0, 0.2), not the expected value 1.5.

Possible cause: Builtin.initialEnv initializes an operator called "inital".
This looks like a typo.

Håkan, this probably belongs to you. Maybee you have already fixed it in our
"branch".
