Hi,
I think you could use the containerView variable in your precondition
expression of your NodeCreationDescription (the completion does not
expose it, but it will be present at evaluation time).
containerView will correspond to the Sirius internal model element, in
your case a DNodeList. You could check the number of ownedElement which
is the feature storing the list elements.
Could you also create a bugzilla to track the hidden variable ?
Regards,
