John,
I am very new to OOP so take this with a grain of salt, but what if you have an abstract or interface class for the two classes (ex. AbstractPersonBean)... and then PersonObj and EmployeeObj would extend that (or employee could extend person i think). Then your return types could be of type AbstractPerson and should not cause any type conflicts...
but again... grain of salt.

Subject: [CFCDev] DAO Inheritance
I have a base object 'person' for which I have defined both a
personObj to hold information and a personDAO to handle persistance. My
person DAO has a getById() function which takes a uuid and returns a cfc of type
personObj.
I now want a new object 'employee' so I create an employeeObj which extends
person, and to handle the persistance I create a employeeDAO which extends
personDAO. employee DAO also has a getById() function which takes a uuid and
should return a cfc of type employeeObj.
My employeeDAO.getById() function is causing me problems. I am trying to
call super.getById() but this returns an object of type personObj rather than
employeeObj.
How can I leverage the DAO code I have written in the parent object?
John
