[keycloak-user] REGISTER event: firstName & lastName always NULL

[Marek Posolda]

Not 100% sure, but I think that you're right and firstName and lastName 
are not available in the REGISTER event. That's because REGISTER event 
is triggered too early - at the stage when userModel doesn't yet have 
firstName and lastName properly set on it.

I think there are some workarounds - for example there is LOGIN event, 
which is send right after the REGISTER. You can track LOGIN events, 
which were sent right after the REGISTER events. I think that firstName, 
lastName should be available in those LOGIN events.
