subclass active record error

Hi, I have a abstract base class and a subclass
this is my script:

Code:

---

entity jpa --class ~.domain.Parent  --inheritanceType JOINED --activeRecord false
field string --fieldName parentp1 --notNull  --sizeMax 14
entity jpa --class ~.domain.Child --extends ~.domain.Parent --testAutomatically --identifierField id --identifierColumn id

field string --fieldName childp1 --notNull  --sizeMax 14

---

and I got those errors when "perform test":

Code:

---

[ERROR] The method findChild(Long) is undefined for the type Child
[ERROR] The method countChildren() is undefined for the type Child

it looks the Parent class must be a activeRecord?

Thank you!
