How are you doing this? Can you post some code? It looks like you are using a class instead of a component:

model M

  Real x;

equation

  der(x) := -1*x;

end M;



model Test

  M m;

  Real x = M; // not correct, class M

  Real x = m.x; // correct, component m.x

equation

  x = m.x; // correct, component m.x

  x = M; // not correct, class M

end Test;

So maybe is the title a bit misleading. I created several components from block and now I want to connect them like in simulink so like working with submodels-ish. Now I packed all of my models into blocks and packaged them into a package and I want to connect them while they are packaged but when I want to check model, I always get this translation errors expected X to be a class but found component instead. I am so confused, I really dont know, what to do or where to check, what am I doing wrong.
