Hey guys I'm looking at using ELMAH for the first time but have a requirement that needs to be met that I'm not sure how to go about achieving...

Basically, I am going to configure ELMAH to work under asp.net MVC and get it to log errors to the database when they occur. On top of this I be using customErrors to direct the user to a friendly message page when an error occurs. Fairly standard stuff...

The requirement is that on this custom error page I have a form which enables to user to provide extra information if they wish. Now the problem arises due to the fact that at this point the error is already logged and I need to associate the loged error with the users feedback.

Normally, if I was using my own custom implementation, after I log the error I would pass through the ID of the error to the custom error page so that an association can be made. But because of the way that ELMAH works, I don't think the same is quite possible.

Hence I was wondering how people thought that one might go about doing this....

Cheers

UPDATE:

My solution to the problem is as follows:

public class UserCurrentConextUsingWebContext : IUserCurrentConext
{
    private const string _StoredExceptionName = "System.StoredException.";
    private const string _StoredExceptionIdName = "System.StoredExceptionId.";

    public virtual string UniqueAddress
    {
        get { return HttpContext.Current.Request.UserHostAddress; }
    }

    public Exception StoredException
    {
        get { return HttpContext.Current.Application[_StoredExceptionName + this.UniqueAddress] as Exception; }
        set { HttpContext.Current.Application[_StoredExceptionName + this.UniqueAddress] = value; }
    }

    public string StoredExceptionId
    {
        get { return HttpContext.Current.Application[_StoredExceptionIdName + this.UniqueAddress] as string; }
        set { HttpContext.Current.Application[_StoredExceptionIdName + this.UniqueAddress] = value; }
    }
}

Then when the error occurs, I have something like this in my Global.asax:

public void ErrorLog_Logged(object sender, ErrorLoggedEventArgs args)
{
    var item = new UserCurrentConextUsingWebContext();
    item.StoredException = args.Entry.Error.Exception;
    item.StoredExceptionId = args.Entry.Id;
} 

Then where ever you are later you can pull out the details by

    var item = new UserCurrentConextUsingWebContext();
    var error = item.StoredException;
    var errorId = item.StoredExceptionId;
    item.StoredException = null;
    item.StoredExceptionId = null;

Note this isn't 100% perfect as its possible for the same IP to have multiple requests to have errors at the same time. But the likely hood of that happening is remote. And this solution is independent of the session, which in our case is important, also some errors can cause sessions to be terminated, etc. Hence why this approach has worked nicely for us.
