> If an entity that is already set to modifiable is updated, then set to modifiable again, the updates will not be flushed on commit.
> This is because there is no check to see if the entity is already modifiable before 
> changing the snapshot to match the current (updated) entity state in the session. On flush, the current state of the entity in the session is compared with its snapshot. Since it is the same, the entity appears to not be dirty, so the updates are not persisted.
> The fix for this is to not change the snapshot when an entity is set to modifiable if that entity is already modifiable.
