Improving the explanation of why Line isn't present would require exhaustively listing all the possible fields/etc that where is _isn't_ valid to assign a Line instance - Line isnt a subtype of String, Line isn't a subtype of List, the List in this field is List<Component> and Line isn't a subtype of Component, etc...
If you can point out in code how you expect to be able to send the Line type (which field in which other type that _is_ present in that list) it would be easier to offer an explanation.
