I use the code below to create nodes in 7.1. The pages are created but not published. Any idea why this is? Also, Visual Studio tells me the code is obsoloete. Is there a newer/better way to do it? This is all I could find.

DocumentType dt = DocumentType.GetByAlias("TextPage");

umbraco.BusinessLogic.User u = new umbraco.BusinessLogic.User(0);

Document doc = Document.MakeNew("Page name", dt, u, parentNodeID);

doc.getProperty("textProperty").Value = "Lorem ipsum dolor";

doc.Publish(u);
umbraco.library.UpdateDocumentCache(doc.Id);
