Model data

###Relational
Database Oct::stores::ParentStore
(
  include Oct::stores::ChildStore

  Table FIRMTABLE
  (
    ID INTEGER,
    NAME VARCHAR(10)
  )

  Join FRIM_PERSON(FIRMTABLE.ID = PERSONTABLE.FIRMID)
  Join FRIM_CEO(FIRMTABLE.ID = PERSONTABLE.FIRMID)
)

Database Oct::stores::ChildStore
(
  Table PERSONTABLE
  (
    ID INTEGER,
    NAME VARCHAR(10),
    FIRMID INTEGER
  )
)


###Pure
Class Oct::models::Person
{
  lName: String[1];
  fName: String[1];
  firm: Oct::models::Firm[1];
}

Class Oct::models::Firm
{
  id: Integer[1];
  name: String[1];
  employees: Oct::models::Person[*];
}


###Mapping
Mapping Oct::mappings::simpleRelationalMapping
(
  *Oct::models::Firm[testInlineMapping]: Relational
  {
    ~mainTable [Oct::stores::ParentStore]FIRMTABLE
    id: [Oct::stores::ParentStore]FIRMTABLE.ID,
    name: [Oct::stores::ParentStore]FIRMTABLE.NAME
  }
  *Oct::models::Person: Relational
  {
    ~mainTable [Oct::stores::ParentStore]PERSONTABLE
    fName: [Oct::stores::ChildStore]PERSONTABLE.NAME,
    firm() Inline[testInlineMapping]
  }
)

Thanks for filing the issue! This has more to do with the generic Query Builder instead of Legend Query app so I'll relabel them.
