Comment passer un objet d'un flow à un subflow

**Khaled.Noordin** · 09/01/2013, 16h51

Bonjour
Je cherche à passer un object d'un flow à un subflow.
L'object en question est une variable d'un flow que j'ai évalué en début de flow et placé en conversation scope, donc le but de l'avoir visible dans le flow et ses subflow, mais arrivé en subflow l'appel de cette objet par EL dans la page web me renvoi vide.
voici le flow parent

En reconsidérant mon analyse de flow,
j'en suis arrivé à la conclusion que je n'avais pas besoin de subflow dans mon cas d'utilisation.
Cela ne résout pas ma question initiale mais au moins j'en arrive à une issue fonctionnelle
que voici

        </transition>
    </view-state>
 
    <end-state id="profileEndFlow" view="externalRedirect:#{from}" commit="true"/>
 
</flow>

alors si quelqu'un a une idée sur la façon de passer des données d'un flow parent à un sublow je serai ravie de connaître le modus operandi.
