ListAdded is not firing when list is created by code

Question

I have an SPListEventReceiver that handles the ListAdded event. If checks that the list is a Document Library, and then adds some fields to the library:

public class ListEventReceiver : SPListEventReceiver
{
    public override void ListAdded(SPListEventProperties properties)
    {
        if (properties.List.BaseTemplate == SPListTemplateType.DocumentLibrary)
        {
            // Add fields here
        }
        base.ListAdded(properties);
    }
}

When a list is created using SharePoint's web UI, the event works perfectly. However, when the list is created by the code below, the event is not fired, and the fields are not added:

SPWeb spWeb = ...;
SPListTemplate listTemplate = ...; //Find relevant DocLib template
Guid newListId = spWeb.Lists.Add(title, description, listTemplate);

EDIT: I do not have the option of changing the EventReceiver - it was created by a third party, and I have no control over it.

Answer 1

ListAdded event runs asynchronously (whereas ListAdding is synchronous). The properties may not be available for updating. This post describes an alternative using ListAdding - Working with ListAdding and ListDeleting Events.

I had a similar Event handling situation with ItemAdded/ItemAdding in a Document library where it worked fine under UI but not for automated upload (using PowerShell). There is a matter of at which point in the event handling the properties should or can be updated. This post explains the various Events and their variations ('-ing', '-ed', etc) - not all properties are available during the synch/asynch event handling - Managing ItemUpdating and ItemUpdated Events

More on getting ListAdded (-ed event handling) to run synchronously - SharePoint 2010 Event Receivers can be Synchronous or Asynchronous

UPDATE: Looking at the update to the question above ("EDIT: I do not have the option of changing the EventReceiver - it was created by a third party, and I have no control over it."). The solutions may be limited as I presume, you do not have access to the event handler code. You may try this change - you can specify the 'ListAdded' event handler as synchronous in its Elements.xml file (within the Receiver tag) - Synchronous.

Here's another link to consider should you regain the handler code - Binding asynchronous event handlers as synchronous

Answer 2

Not certain, but do you have to fire an spWeb.Update() after the add?

And should make sure you have using for your SPWeb object, not modifying directly. eg:

 using(SPWeb oWebsite = SPContext.Current.Site.OpenWeb("Website_URL"))
{
    ...
}

Answer 3

Are you using SPContext.Current to get your SPWeb? Be sure you're using properties.Web or such in an event receiver. If the code isn't being run on the UI thread, SPContext.Current would be null.
