[FLOW3-core] Missing Parts in "The Definitive Guide" for Version 2.0

[Nico Thomaier]

Hi,

in the Blog Example of the "The Definitive Guide" there is missing a important Code Line.

Since the "Safe request methods" are read-only the SetupController won't persist it's Data until 
$this->persistenceManager->persistAll(); is called.

This is missing in the code examples. It would also be nice to have a Link to the corresponding Documentation:

http://docs.typo3.org/flow/TYPO3FlowDocumentation/stable/TheDefinitiveGuide/PartIII/Persistence.html#safe-request-methods-are-read-only

Thanks in Advance
