Whoops! An old version of the model. It should be

model t2
  parameter Integer nu;
  input Integer[nu] vals;
  Integer y;
equation
  y = max({abs(vals[i]) for i in 1:nu});
end t2;

OK; the error-message should be "Could not evaluate structural parameter nu". But it's just a warning since the front-end ceval is not sure if it needs the value or not...

I think Adrian fixed this...

[a.mo:3:3-3:25:writable] Error: Could not evaluate structural parameter (or constant): nu which gives dimensions of array: vals[nu]. Array dimensions must be known at compile time.
