Para dar uma idéia do problema, estou fazendo o Connection to XMPP do código do lado do servidor e passando JID, SID e RID para o client, de onde eu uso prebind / keepalive para true e conecto ao Chat passando JID, SID e RID. A conexão acontece com sucesso. No entanto, quando a lista de bate-papo é carregada, não vejo os usuários ONLINE (mesmo que eles estejam online), No Images set (mesmo quando os usuários têm suas fotos definidas). Quando olho para o Fiddler para resolver esse problema, descubro o motivo pelo qual a segunda resposta ao XMPP, que obtém os detalhes do usuário como presença, as informações do vcard é BLANK. No entanto, não consigo entender o motivo de ter uma resposta BLANK. Você pode me dizer por que é assim?
A seguir, a resposta da solicitação que eu capturei pelo Fiddler:
