Creating master-detail VO in custom AppModule method

Question

Hi.
I need to create master-detail view objects and save them in DB in my custom AppModule Service Interface method.
I have the next master-detail view objects:
RegistryVO (1) -- (*) RegistryItemVO
Also I have a view link for this relationship.
I wrote custom method with next signature:
Integer createRegistry(RegistryVORowImpl registry) {
Then, I added this method to my AppModule Service Interface.
Method works fine, but only master row is created and inserted to DB (only Registry but not RegistryItem). I.e. when I testing this method in EM I fill full RegistryVO with nested RegistryItemVO data but in my method RegistryVO comes without nested RegistryItemVOs.
Then, I added SERVICE_PROCESS_CHILDREN custom property to view link (RegistryVO-RegistryItemVO) as it described in chapter 11.2.5 of Fusion Developer 's Guide for Oracle Application Development.
After that nested RegisttryVO in my method contains nested RegistryItemVOs.
In my custom method i need to set primary key for RegistryVO. So I set it in registryVO to PK attribute and set it in nested registryItems to FK attribute.
But when I doing commit I have an exception:
Exception while executing the business logic: JBO-26048: Constraint "PP_PST_RG_IT_PP_PST_FK" is violated during post operation "Insert" using SQL stat
ement " *INSERT INTO PP_PERSON_ST_RG_ITEM* (PP_PERSON_ST_RG_ITEM_ID,IN_DOCUMENT_ID,POL,FULLNAME,NAME,FULLOT,TIN,D_ROG_DT,D_REEST
_DT,PROCESSING_DT,PROCESSING_STATE_CD,RECEIVE_YEAR) VALUES (:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11,:12)".: ORA-02291: integrity
constraint (PP_PST_RG_IT_PP_PST_FK) violated - parent key not found
It seems that only registryItems are commited in DB. I'm not seeing INSERT for Registry in ServieInterface log...
But if I setting primary key for RegistryVO when I invoking method (if I setting id for registry in test console of EM, not in method) - it's work fine .
What I'm doing wrong ?
How can I create custom method for AppModule Service Interface to create master-detail view objects and set PK for master and FK for details within method ?

Thanks for reply, John.
I have already added master and detail view objects usages to my AppModule Data Model. And yes, I add detail VO as child of master.
It seems that the reason of my problem is another...
I can't create master/detail when I'm setting id of master in custom method. If I set id of master in input parameter (RegisterVORowImpl) then method invokes successfull.
I noted one moment - if I'm not setting SERVICE_PROCESS_CHILDREN custom property for view link, I can set id of master VO inside method. But in this case my master VO haven't got nested RegisterItemVOs.
