Hi all.

Using Umbraco 7.15.3 and everytime i restart my application, then the first time it runs DatabaseContext.Database.GetTransaction() it gets a null exception. If i then skip the error and try to run it again, it works, until next restart.

First it runs GetAll, then i try to insert a comment into the database with the Insert method.

// UmbracoServices.Database is equal to UmbracoContext.Current.Application.DatabaseContext.Database

public static void Insert(Comment newEntry)
{  
    using (var transaction = UmbracoServices.Database.GetTransaction())
    {
        UmbracoServices.Database.Save(newEntry);

        var post = UmbracoServices.Database.SingleOrDefault<Post>(newEntry.PostId);
        post.LastReplyDate = newEntry.CreateDate;
        UmbracoServices.Database.Save(post);

        transaction.Complete();
    }
}

public static IEnumerable<Comment> GetAll(int postId)
{
    var comments = new List<Comment>();

    var query = new Sql().Select("*")
        .From(Constants.TableNames.Comments)
        .Where("postId = @0", postId);

    return UmbracoServices.Database.Fetch<Comment>(query);
}

The error i get looks like this.

The database looks like this.

Does anyone have an idea?
