using a ReactiveRepository to save a new entry with user-provided id doesn't persists the entity

[cambierr]

I just noticed that the .save(Entity entity method doesn't actually saves anything if the entity id is user-provided instead of created by the database (Postgres in my case).

For now, the only workaround I see is to add another id property that can be auto-generated but this is a hugly workaround.

From my understanding, this seems to be due to EntityInformation.isNew(T entity) checking if the id property is different from null.

How could we work around this ?

Repositories assume by new/existing state based on the id. If the entity is null, then we assume the entity is new. You can implement Persistable which provides theisNew() method which is used then to determine whether your entity is new or whether it should be expected to exist.

We have no support yet for optimistic locking (see #93) where we could use a @Version property to determine new/existing state.

Didn't know about that interface ! thank you.
