I suppose con is a collection so you would use : s.con->collect(e | e.name)->excludes(s.name)

hi

I used collect but it does not work, and when I use the string name 'cell'
s.name example <> 'cell' it work.
there is an association "con" between the two elements of the metamodel.
or i must use an helper for collect the name of the element.
thanks
