I have a problem when creating a news item from code. Following this example:
I have this code
var newsManager = NewsManager.GetManager();
var news = newsManager.CreateNewsItem();
"This is some sample content."
news.DateCreated = DateTime.Now;
news.PublicationDate = DateTime.Now;
news.ExpirationDate = DateTime.Now.AddMonths(1);
It executes ok, then I can see the new item in Contents->News in the administration. But then I click on the item to edit it and I get this error (error1.png). You see there is no title, nor contents here. Then I click "Back to all items" and I get second error (error2.png) and I can no longer see the item in the list. I have to go and delete manually database records in order to clear the news list.
I suppose it might have something to do with security and permissions, but there are no examples on how to use it.
