> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-314
> Affects Versions: 2.0.6, 2.1.0
> Reporter: Werner Punz
> Assignee: Leonardo Uribe
> Priority: Critical
> Fix For: 2.0.7, 2.1.1

>
> The optimization done on MYFACES-3111 that skips save descendants children state, passing the state as null revealed the need to check for null on child states.
> This happens only when the row is empty and a new row is created.
