Just a short note. The configuration of the record type is now mandatory for every concrete class. Instead of

> <pre>
> config.tx_extbase.persistence.classes {
>    Organization {
>      mapping {
>        tableName = party
>      }
>      subclasses {
>        Company = Company
>        ScientificInstitution = ScientificInstitution
>      }
>    }
>    Person {
>      mapping {
>        tableName = party
>      }
>    }
>    Company {
>      mapping {
>        tableName = party
>      }
>    }
>    ScientificInstitution {
>      mapping {
>        tableName = party
>      }
>    }
> }
> </pre>

it has to be

<pre>
config.tx_extbase.persistence.classes {
  Organization {
    mapping {
      tableName = party
      recordType = Organization
    }
    subclasses {
      Company = Company
      ScientificInstitution = ScientificInstitution
    }
  }
  Person {
    mapping {
      tableName = party
      recordType = Person
    }
  }
  Company {
    mapping {
      tableName = party
      recordType = Company
    }
  }
  ScientificInstitution {
    mapping {
      tableName = party
      recordType = ScientificInstitution
    }
  }
}
</pre>

I use STI in a complex domain and it works quite well.
