@OnCascade(DeletePolicy.DELETE) does not work

Support
#1

Hello guys,

I have the following entities: Inner, InnerLevel2, InnerLevel3. InnerLevel3 is contained (@Composition) in InnerLevel2 and InnerLevel2 is contained (@Composition) in Inner.

The use case is:

  1. I open the single entity browser I have in my project.
  2. I create the Inner entity.
  3. In the create dialog, I create the InnerLevel2 entity.
  4. In InnerLevel2's create dialog, I create the InnerLevel3 entity.
  5. I click OK on all dialogs and everything is created.
  6. I select the entity from the table, then I press on the button next to the create button.
  7. This button calls a method in a service that deletes the selected item and I go to entity inspector to check whats up.
  8. Inner entity is deleted, but the other entities that SHOULD have been cascaded are still there.

I expected that deleting Inner would cascade the deletion of InnerLevel2 that would cascade the deletion of InnerLevel3. This does not happen.

This is a recurring issue I have in a bigger project of mine.

Platform version 6.10.14

Please tell me if my understanding is correct and if so, why is the expected behavior not happening.

Thanks,
Alex

Hi,
Thank you for reporting the problem.
The problem has been fixed in the 7.1 version. See issue: EntityManager.flush() breaks cascade deletion policy · Issue #785 · cuba-platform/cuba · GitHub
