Features:

In previous versions, a single resource instance was used for performing the operation and generating the response. Now these parts of the request handling are split into distinct steps which each use their own resource instances. As a result, any instance variables stored on the resource during the operation are not present when generating the response.

Any resource instances that are created for the operation processing should be used for the response generation as well.

Non vengono indicati file o test. Inizia tracciando i percorsi di gestione delle richieste per l’elaborazione delle operazioni e la generazione delle risposte, quindi confronta dove vengono create le istanze delle risorse. Il lavoro è completato quando le istanze delle risorse utilizzate durante le operazioni vengono utilizzate anche per generare le risposte, preservando le variabili di istanza impostate durante l’operazione.
