How to update filed in jsonb and other columns in one call

[slovvik]

I have faced a problem in that I can only update the JSON column in my object and can't update other columns.

Let say I have this table definition:

class JsonTestTable(tag: Tag) extends Table[JsonBean](tag, "JsonTest0") {
    def id = column[Long]("id", O.AutoInc, O.PrimaryKey)
    def test = column[String]("test")
    def json = column[JsonString]("json", O.Default(JsonString(""" {"a":"v1","b":2} """)))

    def * = (id, json) <> (JsonBean.tupled, JsonBean.unapply)
  }

and want to update the JSON column and the test column in one query. How should I do that?
I stuck with this:

JsonTests.filter(_.id === 33L).map(o => (o.test, o.json.set(List("c"), JsonString(""" [1] """)))).update(("newValue", "sameAsParameterInSetMethod?"))

but this makes non sens and returns

A query for an UPDATE statement must select table columns only -- Unsupported shape: ProductNode
