Crea flusso di lavoro principale

Il flusso di lavoro principale viene attivato quando l’utente invia il modulo iniziale (RefinanceForm). Il flusso di lavoro seguente

Archiviare Forms To Signis come passaggio del processo personalizzato.

L’implementazione di un passaggio di processo personalizzato è motivata dall’estensione di un flusso di lavoro AEM. Il codice seguente implementa un passaggio di processo personalizzato. Il codice estrae i nomi dei moduli da firmare e trasmette i dati del modulo inviati al metodo insertData nel servizio SignMultipleForms. Il metodo insertData inserisce quindi le righe nel database identificato dall'origine dati aemformstutorial.

Il codice in questo passaggio del processo personalizzato fa riferimento al servizio SignMultipleForms .
