Re: [help-GIFT] CSessionManager.cc:1294:throwing AnVENotFound occured: Could not find Session

[Pruet Boonma]

Hi,

I believe that you havn't open a session before querying. The query
steps should be something like this.

1. open a session (client->server)
<mrml session-id="dummy">
<open-session user-name="a_user" session-name="default_session" />
</mrml>

2. acknowledge session (server->client)
<mrml session-id="1">
<acknowledge-session-op session-id="1" session-name="default_session"
user-name="a_user" />
</mrml>

3. Then, you can do the rest, such as get-server property (client->server)

<mrml session-id="1">
<get-server-properties />
</mrml>


If my memory does not play any trick to me, it should be like this.

Cheers,
pruet
