CreateNewStandardPage not working in build 1210

Posted by Community Admin on 08-Mar-2011 00:00

We upgraded from build 1098 to build 1210. The following block of code was running fine for weeks, but immediately after the upgrade it throws the error: Object reference not set to an instance of an object.
I stopped the code in debug and verified that all the variables that are being used in the method chain are valid and not null.

fluent.CreateNewStandardPage(parentNode)

.Do(pn =>

pn.Title = newPageName;

pn.UrlName = newPageName;

pn.Page.Title = newPageName;

pn.InheritsPermissions = myInheritPermissions;

)

.CheckOut()

.SetTemplateTo(guidTemplate)

.Publish()

.SaveChanges();

Here is the top of the stack trace. The method, MyPageManager.MakeNewPage() is mine.

[NullReferenceException: Object reference not set to an instance of an object.]

Telerik.Sitefinity.Modules.Pages.PageManager.ExecutePublishPageDraft(PageDraft draft, Boolean makeVisible) +1309

Telerik.Sitefinity.Modules.Pages.PageManager.PublishPageDraft(PageDraft draft, Boolean makeVisible) +669

Telerik.Sitefinity.Fluent.Pages.PageDraftFacade.Publish() +251

LessonBuilder.Web.Util.MyPageManager.MakeNewPage(String mainPageName, Boolean isChildToThis, String childPageName, Boolean myInheritPermissions) in C:\CurrentFiles\Projects\LessonBuilder1098\LessonBuilderApp\LessonBuilder.Web\Util\myPageManager.cs:170

Can you verify that this is a problem on your side? If not please advise me what I am doing wrong.
Thanks.

Hi Phil,

This code

var pageTemplate = PageManager.GetManager().GetTemplates().First();

var pageFacade = App.WorkWith().Page().CreateNewStandardPage(PageLocation.Frontend).Do(pg =>

pg.Name = "name";

pg.Title = "title";

pg.UrlName = "someurlname";

pg.ShowInNavigation = true;

pg.Page.Title = "datatitle";

pg.Page.HtmlTitle = "htmldatatitle";

pg.Description = "Some description";

)

.CheckOut()

.SetTemplateTo(pageTemplate)

.Publish()

.SaveChanges();

works fine under SP1.

All the best,

Ivan,
I am also getting this same error in SP1. Here is the code that I am using:

PageManager manager = PageManager.GetManager();

var template = manager.GetTemplates().First();

var newPage = App.WorkWith().Page()

.CreateNewStandardPage(PageLocation.Frontend)

.Do(p=>

p.Name = "FluentAPI Page";

p.Title = "Fluet API Page";

p.UrlName = "fluent-api-page";

p.ShowInNavigation = true;

p.Page.Title = "Fluent API Page";

)

.CheckOut()

.SetTemplateTo(template)

.Publish()

.SaveChanges();

If I take out the ".Publish()" statement, then the code will run and my page is checked out. After deleting the page and adding the ".Publish()" back in, I again get the error. My Stacktrace is the same.

Hello Richard,

I am not able to replicate this issue using the SP1 and latest internal build. The code creates a new page.
