Hi,
I used multitenancy descriminator in single database.

@entity
class Student implements MultiTenant {
static hasMany = [persons:Person]
static mapping = {
persons joinTable:'student_person'

   }

Long tenantId
//...other properties

}

@entity
class Person implements MultiTenant {
static belongsTo =[Student]
static hasMany = [students:Student]
static mapping = {

   students joinTable:'student_person'
 }


  Long tenantId
  //other properties

}

@entity
class StudentPerson {

static constraints = {
 }
    Long studentId
    Long personId
   // String relType

}
student_person table contain student_id,person_id columns only

I got the studentInstance object from studentId

After I use "studentInstance.persons" it will throw the exception no tenant_id on student_person.tenat_id

The generated hql is adding student_person.tenant_id column in the query where condition. It will throw the exception " Unknown column 'persons0_.tenant_id' " in 'where clause' for all join tables.
The generated hql is
select
persons0_.student_id as student_3_48_0_,
persons0_.person_id as person_i4_48_0_,
person1_.id as id1_32_1_,
person1_.version as version2_32_1_,
person1_.tenant_id as tenant_i3_32_1_,
person1_.first_name as first_na4_32_1_,
...........
from
student_person persons0_
inner join
person person1_
on persons0_.person_id=person1_.id
where
? = persons0_.tenant_id
and persons0_.student_id=?

The student_person table does n't contain tenant_id in table

Thanks
Siva.
