ContractDefinitionDeleted event as pre-delete

[tmberthold]

We use various events in an extension, among them the ContractDefinitionDeleted event. The ContractDefinitionDeleted event is, as the name implies, a post-delete hook and is therefore triggered as soon as the contract definition has actually been deleted. For a use case we would like to intervene directly before deletion. Is there already the possibility for this with some kind of pre-delete event or is it intended to create something like a pre-delete event as well?

[ndr-brt]

Events are meant to describe something that "already happened", that's why they are past tense.
I have a question, since the deletion of a contract definition is a sync operation triggerable through an api call, what's the need for a pre-delete? what do you mean with "intervene directly before deletion"?

[tmberthold]

intervene directly before deletion = we wanted to be able to get the assets from the ContractDefinition before the ContractDefinition has been deleted

[ndr-brt]

Couldn't you just do a GET /contractdefinitions/{id}, get the assets using the selectorExpression (that needs to be converted to a QuerySpec and then delete the definition?

An advantage to doing what @ndr-brt suggested is that you also have access to pagination for the assets.

In general, event listeners should execute quickly.
