Indeed! Now it works for me too. JSON Facets seems powerful, but not
friendly to me.
Yonik, thanks for example!

Xavi,

I took  json docs from http://yonik.com/solr-nested-objects/ and just
doubled book2_c3

Here is what I have with json.facet={catz: {type:terms,field:cat_s, facet:{
starz:{type:terms, field:stars_i, domain:{blockChildren:'type_s:book'}} }}}

{
  "responseHeader": {
    "status": 0,
    "QTime": 2,
    "params": {
      "q": "publisher_s:*",
      "json.facet": "{catz: {type:terms,field:cat_s, facet:{
starz:{type:terms, field:stars_i,
domain:{blockChildren:'type_s:book'}} }}}",
      "indent": "true",
      "wt": "json",
      "_": "1448309900982"
    }
  },
  "response": {
    "numFound": 2,
    "start": 0,
    "docs": [
      {
        "id": "book1",
        "type_s": "book",

      {

    ]
  },

                "count": 1
              },
              {
                "val": 5,
                "count": 1
              }
            ]
          }
        },
        {
          "val": "sci-fi",
          "count": 1,
          "starz": {
            "buckets": [
              {
                "val": 2,
                "count": 2
              },
              {
                "val": 4,
                "count": 1
              },
              {
                "val": 5,
                "count": 1
              }
            ]
          }
        }
      ]
    }
  }
}

It works well with *:* too.
