Original description

What version are you using? 0.99

unfortunately, one isnt able to access the Datasource from within an EntityListener.

It doesn't appear that any interface is enforced by @EntityListeners. Getting that Datastore (which I'm assuming is what is meant there) in would be tricky. I'm ok introducing an interface or at least a constructor requirement (maybe an optional constructor?) but that might break existing code.

Using an optional constructor might be pretty useful and probably wouldn't break anything as we'd just fall back to the empty constructor.

I looked in to this and even had it mostly working. Unfortunately, it requires several changes to public APIs that can't be mitigated by simple overloads. I'm afraid this one will have to wait.
