Hi,

I'm using the tool a little time and I'm having some difficulties. I followed the directions on this topic (LINK) and get put to work by reference to UML.

But my objective is to use variables that are in the model or that are declared in code. Below is a summary of the grammar:

import 'http://www.eclipse.org/uml2/3.0.0/UML' as umlMM

MyClassRef:
referencedClass=[umlMM::Class];

IdClass:
MyClassRef |
var={ID};

Assignment:
var=ID EQUALS expression=Expression;

Expression:
Add_Code;

Add_Code:
'ADD_CODE' '(' varClass=IdClass ')';

Only classes derived validates the model, but does not accept the declared variables.
Appreciate the help!

Hi Filipe,

I would try to make following changes.

MyClassRef:
referencedClass=[umlMM::Class];

IdClass:
MyClassRef | [Variable];

Assignment:
var=Variable EQUALS expression=Expression;

Variable:
name=ID;

Expression:
Add_Code;

Add_Code:
'ADD_CODE' '(' varClass=IdClass ')';

I still don't know if it will work, but it's a shot.
