Hi Distrust, Why can't you simply implement it inside of showSettingsAction() method? You NEVER want to fetch data when controller instance is created immediately. In case you want to re-use some logic in other actions (not really your case as you call fetchAll() only) you have got more options: - create protected method inside of the same controller - service methods (in your case it would be SettingsTable class?) - controller helpers - ...?
To follow Mike's answer (and don't think it's correct in your use case) - do not mix service (controller) factory with other logic as he proposed. You can overwrite protected method attachDefaultListeners() in your controller https://github.com/zendframework/zf2/blob/master/library/Zend/Mvc/Controller/AbstractController.php#L304 and attach listeners you need there or use shared event manager?
