Query on polyphomic association
-------------------------------

                 Key: HHH-4504
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4504
             Project: Hibernate Core
          Issue Type: Bug
          Components: query-hql
    Affects Versions: 3.2.6
         Environment: MySQL 5.0.51a-community-nt
            Reporter: Rafael Santini


The following query on a polyphormic association does not works:

from Pessoa where nome = 'Rafael';

Error: Unknown column 'pessoa1_1_.nome' in 'where clause'

Mapping:

<class name="Pessoa" table="bs_com_pessoa">

  <id name="id" type="java.lang.Long">
    <generator class="native"/>     
  </id>

  <joined-subclass name="PessoaFisica" table="bs_com_pessoa_fisica">
    <key column="id_pessoa"/>
    <property column="nome" name="nome" not-null="true"/>
  </joined-subclass>

  <joined-subclass name="PessoaJuridica" table="bs_com_pessoa_juridica">
    <key column="id_pessoa"/>
    <property name="razaoSocial" column="razao_social" not-null="true"/>
    <property name="nomeFantasia" column="nome_fantasia" not-null="true"/>     
  </joined-subclass>

</class>

<class name="Cliente" table="bs_erp_cliente">

  <id name="id" type="java.lang.Integer">   
    <generator class="native"/>     
  </id>

  <many-to-one name="pessoa" class="Pessoa" column="id_pessoa" not-null="true" unique="true" cascade="all"/>

</class>

SQL generated by Hibernate:

select cliente0_.id as id18_, cliente0_.id_pessoa as id2_18_ from bs_erp_cliente cliente0_, bs_com_pessoa pessoa1_ where cliente0_.id_pessoa=pessoa1_.id and (pessoa1_1_.nome like ?) order by pessoa1_1_.nome

There is not pessoa1_1_ in the from clause.
