Re: [Vala] Invalid assignment from owned expression to unowned variable

[Joseph Montanez <jmontanez gorilla3d com>]

Abderrahim,

1)  msg = (owned) msg;
    Results in "No reference to be transferred"

    As to why I am using "out" is because when I was changing the
"msg.response_headers" and the changes where not being reflected back
when I was finished using msg.

2)  public string get_session_id (unowned Soup.Message msg)
    Results in "error: syntax error, `new' modifier not allowed on
creation method"
    This tries to initialize the variable msg
