Hibernate, mapping of foreign keys that have been generated by a sequence in the parent table

Hibernate, mapping of foreign keys that have been generated by a sequence in the parent table

hope this fix your issue
Is there a mapping which tells hibernate to use the newly generated PK of the parent object as FK in the child objects, or do I have to persist the child objects separately with the FK manually set?
code :
Contract contract = new Contract();
...
ContractSearchtags tag = new ContractSearchtags();
...
contract.getContractSearchtagses().add(tag);
tag.setContract(contract);

session.save(contract);
public void addToContractSearchtagses(ContractSearchtags tag) {
    contractSearchtagses.add(tag);
    tag.setContract(this);
}
Contract contract = new Contract();
...
ContractSearchtags tag = new ContractSearchtags();
...
contract.addToContractSearchtagses(tag);

session.save(contract);
Breeze server-generated keys of guids saving temporary client keys to database

it fixes the issue If you are working with Guid's, I think best practice should be to generate them on the client. You can use the breeze.core.getUuid() method ( currently undocumented) to generate client side Guid's.
If you really want to generate them on the server, then you will need to use a Breeze KeyGenerator. There is more information on this topic here: Search for Key Generator within this page and within the API docs.

like below fixes the issue In short, Entity Framework 'abstracts that away'.
Its clever enough to recognise that your FKs represent relationships and so allows you to work with the objects themselves. So instead of having you worry about checking the FK constraint, etc. for, say, SolutionTypeId - you just need to add a SolutionType object to your Device object and let Entity Framework sort it out. (Of course, this causes problems if you try to add a new SolutionType that violates the SolutionType PK so maybe you need to first find an existing object from the SolutionTypes table).

like below fixes the issue The ID of the disk is sufficient to uniquely identify a disk. So there's no reason to include the ID of the user into the disk's primary key. It would even be an extremely bad idea, because that means that if a disk's user changes, you would need to modify the primary key.
Same for a file. A file ID uniquely identifies a file. So there's no reason to add the disk ID into the primary key of a file.

This might help you Yes it is. As per official documentation (i left only valuable information) "Lookup values are added as new fields onto the stream". So u need just to put step "Filter row" in Flow section and check for "id" which suppose to be added in "Existing Id Lookup" step.
