[Flow] Dynamically add element to array collection with fluid form

[Carsten Bleicker]

The dynamic fields are not known to trusted properties wich is usualy build up by any formfield viewhelper.
I think in case of dynamic fields you need an initializeFooAction() wich allows these dynamic subsets.

something like this:
	/**
	 * @return void
	 */
	protected function initializeCreateAction() {
		$databaseServerMappingConfiguration = $this->arguments->getArgument('databaseServer')->getPropertyMappingConfiguration();
		/** @var array $databaseServers */
		$databaseServers = $this->request->getArgument('databaseServer');
		foreach ($databaseServers as $key => $server) {
			$databaseServerMappingConfiguration->forProperty('databaseUsers.' . $key)->allowAllProperties();
		}
	}
