This is kind of a lazy question of me but that’s why I bought Jmix. Can you show me an example of a custom action that duplicates an entity and (optionally) opens the Edit screen? BTW This really should be a standard action. Thanks.
Could you clarify your question a little bit? Do you mean user action in browser, when the application is running, like ‘Copy’ action for a record?
Or do you want to duplicate an Entity in Jmix tree in Studio as developer?
This example shows how to copy entities in a browse screen: https://demo.jmix.io/sampler/#main/0/sample?id=copy-action
