Hi Michal,
I have no idea as to how this would be represented in an UML model, but
I do know UML has no "ordered" reference : everything is unordered (see
also my answer on
http://lists.gforge.enseeiht.fr/pipermail/topcased-users/201 0-May/003777.html
).
I believe your choices are to either use the "sortedBy" OCL operation in
order to properly order your ValueSpecifications (or ControlFlows) or
make use of recursive Acceleo Queries or Templates.
As I said earlier, I haven't got even the slightest idea as to how your
diagram would be represented in UML, so I can't really help with the OCL
you'd need.

Hi Michal,
Sorry, I realize I let one of your posts slip through last week.
Your code ... scared me :p.
Couldn't you at least use a recursive template such as
[for (i : InitialNode | a.ownedElement)]
[getNodeFlow(i)/]
[/for]
[template public getNodeFlow(node : InitialNode)]
node.outgoing.target.name;
[if (not outgoing.target.outgoing.oclIsUndefined())]
[getNodeFlow(outgoing.target)/]
[/if]
[/template]
