Dear colleagues,

I am new in M2M (I work with it as part of the work for my PhD) with ATL
and so please excuse me if I make simple questions.

I read the ATL User guide and have an issue when writing the rules:

rule Goal2UseCase {
from
i : SAG!Goal
to
o_1 : SUC!UseCase (
name <- i.name,
interacter <- thisModule.resolveTemp(i.depender, 'o_n'),
interacter <- thisModule.resolveTemp(i.dependee, 'o_n')
)
}

rule Actor2Role {
from
i : SAG!Actor
to
o_n : SUC!Role (
name <- i.name
)
}

The problem is in adding the line:
interacter <- thisModule.resolveTemp(i.dependee, 'o_n')
If I ommit this line the code works fine. The dependee reference of
SAG!Goal is optional and can be multiple. The depender reference has
always a unique value.

How can I add the optional multiple references to SUC!UseCase.interacter?

Thank you,
Nikos Spanoudakis
