SPContext.Current throws SecurityException for most properties

Question

Many properties for SPContext.Current objects throws SecurityException. (Like SPContext.Current.Fields, many properties in SPContext.Current.Site (see details).

• DLL Is in GAC
• Using Site Owner when trying those properties.
• Maybe it has to do something with database access? However SharePoint site is working - I can add list items, etc.
• Application Pool has permissions to database. Should I set application pool account as farm admin or it is not necessary?
• In my Development environment, it just works.

Where could be the problem? Could someone, please, point me in right direction?

Thank you.

Event Viewer has bunch of errors

• for SharePoint search Indexer (i don't have a working search at the moment, I just hope it is not the problem)

• And there is an error about Alternate Access Mapping (Sometimes I access SharePoint from IP address, not from hostname, as hostnames do not resolve in VPN for me, but that's a different problem):

  The description for Event ID ( 8214 ) in Source ( Windows SharePoint Services 3 ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: A request was made for a URL, http://192.168.0.9, which has not been configured in Alternate Access Mappings. Some links may point to the Alternate Access URL for the default zone, http://serveris. Review the Alternate Access mappings for this Web application at http://serveris:38590/_admin/AlternateUrlCollections.aspx and consider adding http://192.168.0.9 as a Public Alternate Access URL if it will be used frequently.

Answer 1

I know I have had to use code to ensure that the SPContext exists when executing from a non-web context.

public static void EnsureSPContext(this SPWeb web)
    {
        // Ensure HttpContext.Current
        if (HttpContext.Current == null)
        {
            HttpRequest request = new HttpRequest("", web.Url, "");
            HttpContext.Current = new HttpContext(request,
              new HttpResponse(TextWriter.Null));
        }

        // SPContext is based on SPControl.GetContextWeb(), which looks here
        if (HttpContext.Current.Items["HttpHandlerSPWeb"] == null)
            HttpContext.Current.Items["HttpHandlerSPWeb"] = web;

    }

Ahh, the issue is now resolved after stepping already like 3rd time on the same rake.

It was happening in WebPart constructor (do not know if it plays a role, but inherited from Microsoft.SharePoint.WebPartPages.WebPart) and there the SPContext object was messed up.

Interesting that it works in my development environment.
