[Mono-list] First load error

[Lorenzo Viola]

Hello, I'm struggling on this problem from 2 days, I need some help...

I'm developing a website using vs2005,and then I deploy it to a debian / 
apache2 / mod-mono box

On the windows machine (vista + iis) I get no problem...when launching 
the application
from a browser on the linux machine, the first time a user browse the 
home page gets the below message...

refreshing the page, the problem gets away, without problem.

My real problem is that I can't get a real debug...

On mono, there is some variable still null at startup...
but I can't find which it is...


I've tried :
Console.Error.WriteLine(ex);

But I get no error inside the apache2 log...

The only way I found, is to place inside global.asax the following :

    void Application_Error(object sender, EventArgs e)
    {
        string EventLogFile = "/var/www/xxxxxxxxxx/xxxxxx.log";
        StreamWriter sw = new StreamWriter(File.OpenWrite(EventLogFile));
        sw.AutoFlush = true;
               
        string sError = Server.GetLastError().ToString();
        string sTrace = Server.GetLastError().StackTrace.ToString();
        sw.WriteLine("###################### ERROR ");
        sw.WriteLine(sError);
               
        string sErrorInner, sTraceInner;
        if (Server.GetLastError().InnerException != null)
        {
            sErrorInner = Server.GetLastError().InnerException.ToString();
            sTraceInner = 
Server.GetLastError().InnerException.StackTrace.ToString();
            sw.WriteLine("###################### ERROR INNER ");
            sw.WriteLine(sErrorInner);             
        }      
        sw.Close();
    }


but I get the same message below...

I read about the tracing system, but it looks an overhead to me...

There is any other way than installing a whole linux system with some 
IDE like monodevelop ?
it takes a lot of time...


Best Regards



ps...the only strange thing I do is loading at preinit a different 
masterpage...


    protected override void OnPreInit(EventArgs e)
    {
        try
        {
            GetCookie();

            string sMPFile = "~/templates/t" + Session["soc"] + 
"_home.master";
            if (Session["op"].ToString() == "page")
                sMPFile = "~/templates/t" + Session["soc"] + "_page.master";

            base.MasterPageFile = sMPFile;
            base.OnPreInit(e);
        }
        catch (Exception ex)
        {
            Console.Error.WriteLine(ex);
            throw;
        }
    }



(this is error I get...)
