I managed to get a value in my sequence. The OCL query so far looks like:
helper context EPK!Event def: isConditionExpressionEvent() : Boolean =
EPK!ControlFlow.allInstances() -> collect(i | i.target)-> asSet() -> intersection(self.id -> asSet()) -> asSequence()
So far I have in my Sequence a '2'. That is what I expected. My next step is now quite hard and I don't know how to solve. If I do the same step in SQL it would be something like:
select (f | f.source where f.target=Sequence('2'))
How could I do something like that?
Thanks for your help...
Cheers Roger

Ok, so far so good.
Now my last question for today, hopefully.
In the where clause i have now, Sequence('2'), but I want to have this more general, is it possible to use it like an array?
Lets say, If I have more than one Sequence.
Example:
Sequence{1,2,3}
Sequence{3,4,5}
Sequence{576,4,67}
Is it the possible to get access just to the first wth a statement like Sequence{0} or something else?
Thanks.

Ok, I do not understand you 100%, is there no possibility to get the attribute target then? What should I do instead.
1) My problem is that I first need the target from the event where the id is like the target. That is working (first part of OCL statement).
2) Then I need attribute source where the f.target is like the values I get from the sequence in the first statement. This is were I am actually on and you try to help me.
3) I need to check if the source is included in the XOR element. This is I think also not a problem. I try it like that...
-> includes(EPK!XOR.allInstances() -> collect(d | d.id));
So thanks for your help....
