I have an entity Person and want to create another entity ContactPerson which extends Person. how do I implement this? On the Parent Class dropdown menu the entities I created do not appear there.
Have you seen this sample project: https://github.com/cuba-platform/sample-entity-inheritance ? (Also available in Studio on the Samples tab).
How many screens will you use, one for Person and one for ContactPerson ? In that case I will be interested by the way you designed the said screens, if you mind to share.
