[jira] [Created] (ATLAS-709) Creating an instance with
bi-directional reference does not set the reverse reference
Prasad S Madugundu created ATLAS-709:
-----------------------------------------
Summary: Creating an instance with bi-directional reference does not set the reverse reference
Key: ATLAS-709
URL: https://issues.apache.org/jira/browse/ATLAS-709
Project: Atlas
Issue Type: Improvement
Reporter: Prasad S Madugundu
1. I have defined 2 classes (DeletePackage_Account and DeletePackage_Customer) with a bi-directional reference (DeletePackage_Account.primaryCustomer and DeletePackage_Customer.ownsAccount).
2. I have created instance of the 1st class (DeletePackage_Account) and got GUID.
3. I have created instance of the 2nd class (DeletePackage_Customer) and set the GUID of the first instance (ownsAccount) for establishing the bi-directional reference between these instances.
4. If I GET the first instance (DeletePackage_Account), I expect that the reference (primaryCustomer) is created to the 2nd instance. But, it does not.
I am sending the JSON for all the above 4 steps.
Register types request (DeletePackage_Customer and DeletePackage_Account that have bi-directional reference as highlighted in bold below)
