Keeping an exact reference to source model element [message #990214]

Hi! I have a simple rule:

rule Formular2GFElement {
  from
    c : UML!Class(
      c.isFormular
    )
  to 
    gf : GF!FGUmlLinked (
      name <- c.name,
      umlElement <- c,
      child <- c.attribute -> 
        collect(a | thisModule.FProperty2GFElement(a))		
    )
}

umlElement is of type UML!NamedElement. However, with traceability links it's resolced to 'gf' itself ('/'). How could i resolve it to 'c'?

Many thanks in advance!

If you use refining model, you could try this:

rule Formular2GFElement {
  from
    c : UML!Class(
      c.isFormular
    )
  to 
    out: UML!Class(
        ),
    gf : GF!FGUmlLinked (
      name <- c.name,
      umlElement <- c,
      child <- c.attribute -> 
        collect(a | thisModule.FProperty2GFElement(a))		
    )
}

The first element of the to clause is refined to the first element in the from clause. So you need to break the identity between c and gf, which is wrongly established. By specifying a dummy element in the to clause, gf won't be the same as c.

Thank you for you answer.

I'm not using refining model, just generating a complete new (kind of decorator) model for the source model.

After a few hours of frustration I've discrovered that imperative assigments will not follow traceability links and found this solution:

rule Formular2GFElement {
  from
    c : UML!Class(
      c.isFormular
    )	
  to 
    gf : GF!FGUmlLinked (
      name <- c.name,
      child <- c.attribute -> collect(a |
        thisModule.FProperty2GFElement(a))	
    )
  do {
    gf.umlElement <- c;
  }
}

Like this:

umlElement <:= c

(assignment instead of binding)
