Hi, I am working with the Adapter. I have a CaseEntity which may or may not have a related BankAccount entity. I am retrieving the BankAccount as below, and am struggling to find a way that I can use to test whether there is a related BankAccount or not other than wrapping the whole thing in a try...catch. Can you tell me if this is the correct way, and if not suggest another?

Thanks

CaseEntity selectedCase = new CaseEntity(1); myAdapter.FetchEntity(selectedCase);

// Now find it's related bank account in the join table selectedCase.CaseBankAccount = (CaseBankAccountEntity)myAdapter.FetchNewEntity(new CaseBankAccountEntityFactory(), selectedCase.GetRelationInfoCaseBankAccount());

CaseEntity selectedCase = new CaseEntity(1); myAdapter.FetchEntity(selectedCase);

// Now find it's related bank account in the join table selectedCase.CaseBankAccount = (CaseBankAccountEntity)myAdapter.FetchNewEntity(new CaseBankAccountEntityFactory(), selectedCase.GetRelationInfoCaseBankAccount());

After that code, do: if(selectedCase.CaseBankAccount.Fields.State==EntityState.Fetched) { // bankaccount available }

I would use prefetch paths and then test for nulll on CaseBankAccount...
