[Flow] Problem to follow the "Definitive Guide"

[Steffen Wickham]

Hello Jonas,

The Definitive Guide is a bit outdated. As of Flow 2.0(?) there is a new 
security feature which allows to safe data if the request method is not 
GET nor HEAD. You have to add a 
"$this->persistenceManager->persistAll();" before returning any value or 
checking if the data had been saved. A more secure way will be to add 
the following lines instead, so only your designated object will be 
persisted:

$this->persistenceManager->whitelistObject($blog);
$this->persistenceManager->persistAll(TRUE);


Hope it will work. :)

All the best,
Steffen
