LibrariesManager.Lifecycle.GetLive returns null even though - Sitefinity - Front- & Back-End Development

I'm trying to extract the URL for a published document in a custom widget built in an external project.

The code is as follows:

01.if (LinkToTermsAndConditions != Guid.Empty)

02.

03. var doc = Telerik.Sitefinity.App.WorkWith().Document(documentGuid).GetLive().Get() as Telerik.Sitefinity.Libraries.Model.Document;

04. //LibrariesManager librariesManager = new LibrariesManager();

05. //var document = librariesManager.GetDocuments().Where(d => d.Id == documentGuid).FirstOrDefault();

06.

07. //if (document != null)

08. //

09. // document = librariesManager.Lifecycle.GetLive(document) as Telerik.Sitefinity.Libraries.Model.Document;

10. //

11.

12. TermsAndCondtions.HRef = doc.Url;

13.

I've tried both the Fluent and normal approaches and in both cases if I just get the document, it retrieves it successfully but as soon as I try to get the current live version, it returns null.

In line 3 above, the Fluent version, I get an exception "An exception of type 'System.Reflection.AmbiguousMatchException' occurred in mscorlib.dll but was not handled in user code"

However when I run:

1.Telerik.Sitefinity.App.WorkWith().Document(documentGuid).Get().Url

I get a document URL.

I've confirmed that the document, a PDF, is definitely published.

Why does the call to Lifecycle.GetLive always return null?

Hello Jacques,

How the Id of the document is get? Testing the sample from that article:
http://docs.sitefinity.com/for-developers-query-documents, seems working fine with both APIs using the following code:
Native API:

private Document GetDocumentNativeAPI(Guid masterDocumentId)

LibrariesManager librariesManager = LibrariesManager.GetManager();

Document document = librariesManager.GetDocuments().Where(d => d.Id == masterDocumentId).FirstOrDefault();

if (document != null)

document = librariesManager.Lifecycle.GetLive(document) as Document;

return document;

Fluent API:

private Document GetDocumentFluentAPI(Guid masterDocumentId)

return App.WorkWith().Document(masterDocumentId).GetLive().Get();

The document is get by:

var libManager = LibrariesManager.GetManager();

var document = libManager.GetDocuments().Where(d => d.Title == "MyDocumentName").FirstOrDefault();

var liveDocFluent = GetDocumentFluentAPI(document.Id);

var liveDocNative = GetDocumentNativeAPI(document.Id);

We are experiencing the exact same issue described by Jacques when retrieving DynamicContent items. Consider this code:

Guid id = new Guid("ac5ccbf3-1c23-67bb-b384-ff0000f3621c");

DynamicModuleManager manager = DynamicModuleManager.GetManager( string.Empty );

var master = manager.GetDataItems( "Telerik.Sitefinity.DynamicTypes.Model.Procedures.Procedure" ).Where( i => i.Id == request.Id ).FirstOrDefault(); // returns live, visible item.

var item = manager.Lifecycle.GetLive( master ); // returns null

var masterTwo = manager.GetDataItem( "Telerik.Sitefinity.DynamicTypes.Model.Procedures.Procedure", request.Id ); // returns live, visible item.

var temTwo = manager.Lifecycle.GetLive( masterTwo ); // returns null

As far as I can tell, the master version returned from Sitefinity is the current version---no draft versions were created after the most-recent master version and all of the master item's properties suggest it is the published version---so that leaves us with this ugly workaround:

// If the item is null and the master version is the published version, use the master version.

if ( item == null && master.Id.Equals( id ) && master.Status == ContentLifecycleStatus.Live && master.Visible )

item = master;

Is there a reason manager.Workflow.GetLive() is not returning the published version of a content item even though one exists?
