Spring-data refresh an object after saving related objects? The problem is pretty straightforward: There's a user table, and then there's a permission table that has a foreign key to the user table (and other tables, depending on the permission, but only the relation to the user object is relevant to this question.

I thought I could use the then function, as the doc states: Error signal is replayed in the resulting Mono My problem can be reduced to the minimum (Kotlin) unit test: @Test fun fluxTest() { val flux = Flux.just("willFail", "willSucceed") .flatMap {...
