Hi! So, I made a news system on my website where me and the other users can publish, delete and edit simple news.

Here's the problem: When trying to edit/delete an existing news I get that Object reference not set error!

Here's how I did it: I make a request with ajax for an aspx page which edits the document or deletes it.

this is the request that it sends (cancella.aspx would be delete.aspx in english).

<code> http://localhost:28799/umbraco/cancella.aspx?id=1150 </code>

here's the code in that page

<code>

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using umbraco.cms.businesslogic;

using umbraco.cms.businesslogic.web;

using umbraco.NodeFactory;

public partial class cancella : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {

        if (Page.Request.QueryString["id"] != "")

        {

            int id = Convert.ToInt32(Page.Request.QueryString["id"]);

            if (id != 0)

            {

                Document doc = new Document(id);

                doc.UnPublish();                

                umbraco.library.UnPublishSingleNode(id);

                umbraco.library.UpdateDocumentCache(id);

                doc.delete();

            }

        }

    }

}

</code>

The idea would be to instantiate the node, unpublish it and then delete it.

I've tried some different things, but it won't matter what I do, when I instantiate the Document, every operation i try to do on it gives that error.

If someone could be so kind to help me it would be great!
