$currnt is not working for arrays of relations, for example:

entity: FirstEntity
items:
   firstEntity{1...10}:
      name: 'FirstEntity($current)" # works

entity: SecondEntity
items:
   secondEntity{1...10}:
      name: 'SecondEntity($current))' # works
      simpleRelation: '@firstEntity($current)' # works
      arrayRelation:
         - '@firstEntity($current)' # does not work, always gives '@firstEntity1'
         - '@firstEntity($current + 1)' # does not work, always gives '@firstEntity2'

It doesn't also get current for the array index of an array field, because it is always 1, even when there is more than one entry in the array.
