Null Database Object in my Scope Provider

[Brendan Enrick]

Hello,

In my ScopeProvider class when I call the GetNewObjectScope() method the Database object it uses is sometimes null and I get a null reference exception.

static public IObjectScope GetNewObjectScope()
{
    Database db = Database();

    IObjectScope newScope = db.GetObjectScope(); // Null Reference here
    return newScope;
}

Thanks for the help,
Brendan

Hello Brendan Enrick,

certainly the database could not be opened in this circumstance. Are you using multiple threads so that another one is calling db.Dispose() incorrectly? What else are the conditions to produce this behavior?

All the best,

It is a web site so there are multiple threads. I am not directly calling Dispose on the db object, but I do dispose of the ObjectScope. Does that call dispose on the db object?

Hello Brendan Enrick,

that is strange then, especially your statement that it is happening _sometimes_. We need to find out why only sometimes - can that be correlated to a significant other event? A more complete stack trace would also be good to find the reason why.

Kind regards,
