Hi,

I have instances of type X, which are represented as a square node.
I have an ordered set of X.
I would like to create and edge between each consecutive instances of X in the ordered set.

Is there any way to do that ? I tried but without success...
thanks in advance

Hi,
you should be able to do that by using a Relation Based Edge and then using a query with "siblings" to retrieve the target element. Something like "aql:self.followingSiblings()->first()"

You might want to restrict to a specific feature using a query similar to this one (used in the case of the eClassifiers containment reference): "aql:self.followingSiblings()->select( s | s.eContainingFeature().name = 'eClassifiers')->first()"

Dear Julien,

To do this, you should use a Relation Based Edge.
In the Target Finder Expression you should use a Java service to retrieve the consecutives instances of X.
