I have an emfatic file with textual notation from a metamodel:

class Element {
  attr int[1] min;
  attr int[1] max;
}

class SubElement extends Element {
}

I want that the class SubElement automatically assign a value to the variable min and max in the emfatic file.

I've tried:

class SubElement extends Element {
    min = 0;
    max = 1;
}

And this:

class SubElement extends Element {
    Element.min = 0;
    Element.max = 1;
}

Or:

class SubElement extends Element { 
    super.min = 0; super.max = 1; 
}

But without success. How can I fix this?

Fabio,

Better to ask about Emfatic on the eclipse.epsilon forum. I doubt what
you're showing can work because Ecore itself doesn't allow you to
override feature defaults in a derived class.
