SpringDataNeo4j-4: BeforeSaveEvent doesn't invoked on nested entities

Question

Have a trouble with nested entities while calling Neo4jTemplate.save(...).

Actually yes, nested entities being persisted as well, but BeforeSaveEvent only invoked on parent entity.

In BeforeSaveEvent, I populate uuid and timeCreated fields for all entities.

I don't want to create this value by myself in class constructor.

So, I'm considering the following solutions:

make it somehow work as I expected (a tough one).
do not even try persist nested entities and persist all entities in a separate way...
create uuid and timeCreated in class constructor
use external library (most unlikely)

Any advice?

I've edited your question to [format code elements](http://stackoverflow.com/help/formatting) as code. I fixed a typo (possibly) by changing the second `uui` to `uuid` to match the first `uuid`. — Wai Ha Lee, Dec 07 '15 at 17:17

This is a known issue: https://jira.spring.io/browse/DATAGRAPH-710 but hasn't been assigned to a specific release yet.

In the meanwhile, perhaps you can use an unmanaged extension that makes use of a transaction event handler to do the job. If you go this route, the GraphAware TxDrivenModules will help.
