Hello,

I am trying to figure out how to set the connection complete precondition that will prevent this type of association from being allowed in my model:

index.php/fa/39495/0/

When I am in the editor I can use the interpreter to figure out all of the ancestors of Element1 using [self.ancestors()/] but I do not know how to translate this to aql for use in the Connection Complete Preconditions box for my edge creation tool. I tried aql: preTarget.differs(preSource.ancestors()) similar to what is in the example here: https://wiki.eclipse.org/Sirius/Tutorials/AdvancedTutorial#Precondition, but it unfortunately doesn't work.

Some guidance would be greatly appreciated
