ERXEOControlUtilities.createAndInsertObject

I'd recommend not doing this in awakeFromFetch, but making this a step in your migration to clean-up your DB/object graph. 1,500 new objects is a light amount of processing and will keep your model object's code clean.

I know that would be a simpler solution, (and propably will do it) but I am still curious why the code does not work.

I am working with shows, that should have contracts.

That was only discovered after some shows (let's say 1500) had already been in the database.

So I created a new entity Contract, that has a not null relation to show, get's it's primarykey propagated from the show which owns the destination. If the shows is deleted, the contract is deleted (Cascade), like so:

I thought that with the code:

public void awakeFromFetch(EOEditingContext eo){
if (contract()==null){
Contract newContract = new Contract();
newContract.setContractAmount(new BigDecimal(0.0));
newContract.setContractDescription("tempDescription");
newContract.setContractRemarks("tempRemarks");
newContract.setContractType(ContractTypeEnum.RENT);
setContractRelationship(newContract);
eo.saveChanges();
}

}

In the extended class of the _Show this would make sure that everything gets filled, in the case a contract has not been created as it does with new shows because it is an old show.

Alas, that does not seem to be the case. What should I do to create a contract the moment an old show does not have a contract?
