Hi all,

I work on wizard, that creats a generalization link between 2 classes.

my guard section is
guard{
var class1 : ecore::EClass;
var class2 : ecore::EClass;
if (self.isTypeOf (Collection) and self.size() = 2
and self.forAll(s|s.isTypeOf(ecore::EClass))){
class1 = self.at(0);
class2 = self.at(1);
}
return class1.isDefined() and class2.isDefined();
}

I want to create a link from class1 to class2, but when I selected 2 elements in the model - they are ordered in Collection not in the way I have chosen them (but alphabetically).

Example: classes A and B in the model
try to select A then B - Collection:(A,B)
try to select B then A - Collection:(A,B) also

I also tried to use .last() method and result was the same
How can I overcome it?

Hi Daria,

Unfortunately, the EMF editor does not preserve the order in which elements were selected (this is a more general issue [1]) so I'm afraid there's not much we can do about this.

Cheers,
Dimitris
