pre(x) outside a when clause

[Lennart Ochel]

The following model simulates without any error message:

model test
  Real x(start=1) = pre(x)+der(x);
end test;

x is a continuous time variable and it is not allowed to use pre for it outside a when clause.

The Question is were should we detect that? In the Backend or Frontend?

[Martin Sjölund]

Backend of course. The frontend does not know if it is discrete-time or not.
