Hi all;
I am exposing a codeunit with a function that i want to use inside my published page. Till here everything is allright,
but when I try to consume this codeunit I have this error : Parameter devis in method LancerDevis in service DevisVC is null!

Sounds like you are passing a null parameter. If you can post the code you are using to call the webservice, that would be helpful.

Thanks for replay

public void Button1_Click(object sender, EventArgs e)
        {
            
                      
            // Creation de l'en-tête Devis
            var Nouv_Dev = new DevisVC();
            Dev_srv.Create(ref Nouv_Dev);
            Nouv_Dev.Délai_de_validité = int.Parse(TB_DVal.Text);
            TB_No.Text = Nouv_Dev.No;
            TB_DatDev.Text = Nouv_Dev.Document_Date.ToShortDateString();
            //TB_Statut.Text = Nouv_Dev.Status.ToString();
            CB_VC.Checked = Nouv_Dev.Vente_à_Credit;
           // Creation ligne Devis
            Nouv_Dev.SalesLines = new Sales_Quote_Line[6];
            for (int i = 0; i < 6; i++)
            {
                Nouv_Dev.SalesLines[i] = new Sales_Quote_Line();
            }
}
private void Button2_Click(object sender, EventArgs e)
        {
           Dev_srv.UseDefaultCredentials = true;
           Dev_srv.LancerDevis(Nouv_Dev.Key);
           Dev_srv.Update(ref Nouv_Dev);
        }

After the creation of the quote with Button1, I want to release it by clicking Button2

You might try this:

private void Button2_Click(object sender, EventArgs e)
        {
           if(Nouv_Dev != null && Nouv_Dev.Key != null)
           {
                    Dev_srv.UseDefaultCredentials = true;
                    Dev_srv.LancerDevis(Nouv_Dev.Key);
                    Dev_srv.Update(ref Nouv_Dev);
           }
        }

From my understanding, it is likely you are doing this from an ASP.NET application, and all of the objects you are relying on may not be in a consistent state.

I think you have two variables with name Nouv_Dev. One defined in the Button1_Click into which you are reading the data, and one "global" which you are using in the Button2_Click, which is not initialized...

Hi all,
I resolved it .
All what i have to do is to re-read the quote.

protected void Button2_Click(object sender, EventArgs e)
        {

            Nouv_Dev = Dev_srv.Read(TB_No.Text);
            Dev_srv.LancerDevis(Nouv_Dev.Key);
            
                            
        }

thanks for all.
