Call.getProperty returns always null on the client

[Alex Dovlecel]

Hello 
Is this normal? 

This is the code : 

private static void displayCallProps(Call call)
{
        for( Iterator it = call.getPropertyNames() ; it.hasNext() ; ) 
        {
                String s = (String) it.next() ; 
                System.out.println("  + " + s + " : " + call.getProperty( s ) ); 
        }               
}

And even if I do : call.setMantainSession( true ) ; when displayCallProps( 
call ) returns null to all the fields. I have also tried to set an user and a 
passwd but with no success :o((( 

And how can I add some Header infos? With addHeader not worked :o((( 

I am using the 1.0 version... should I use the CVS or nightly builds ?
