Unable to build Projection with nested type

[nhatnguyen26]

Consider a query with this structure

{
        id
        type1 {
            subtype1 {
                id
                name
            }
            name
            subtype2 {
                id
            }
            subtype3 {
                ebayPictureUrl
            }
        }
    }

Using the code generated from this plugin would generate a ProjectionRoot, when traverse the project, once reach the nested projection, there is not a way to come back to the parent level and keep traversing

This way of building will not work

new QueryProjectRoot().
  id()
  .type1()
  .subtype1()
  .id()
  // getParent() and getRoot() is returning Object so it can't be used to traverse back without casting
  .subtype()

A work around seem to be manually build each level as a fileld projection itself but it will not be type/syntax safe

new QueryProjectRoot().
id().
getFields().put("type1", <type1projection building>)

@nhatnguyen26 can you share your example schema so we can take a look?
