Hi Marcus,

With SP3 there was some remodelling in how a EPiServer handles the initialization of the application. This was because we were fixing some bugs with enterprise installations and also a step towards making EPiServer working on IIS7 (We're not there yet but in the upcoming R2 release we'll have support for IIS7).

These changes however made it so that it's not possible to hook into the datafactory events in Application_Start. Instead we first hook into Application_FirstBeginRequest and then we have a instance of the DataFactory to work with. Something like this:

protected void Application_Start(Object sender, EventArgs e)     
{         
	EPiServer.Global.Application_FirstBeginRequest += new EventHandler(Global_Application_FirstBeginRequest);  
}

void Global_Application_FirstBeginRequest(object sender, EventArgs e)     
{   
	EPiServer.DataFactory.Instance.SavingPage += new PageEventHandler(Instance_SavingPage);     
}

void Instance_SavingPage(object sender, PageEventArgs e)     
{         
	//Insert magic here.     
}

Thank you! It works fine now.

Got a similar problem after upgrading and have no clue how to fix it:

Got the site working again. Had to remove <add name="BlogEventHandlers" type="EPiServer.Blog.EventHandlers, EPiServer.Blog" /> from web.config and now the Blogg stopped working correctly. Guess the demo package has to be updated to reflect that changes described above.

Hello everyone,

We've now researched this abit more indepth and discovered that both these issues (Marcus aswell as Oskars) should have worked in SP3.

There shouldn't have been necesary to change anything in global.asax.cs or in the demo package for this to work.

The problem is that we made a mistake when the code was written. We've found the error in our code and corrected it. We're building a new version of SP3 as I'm typing this that will fix it. It will be available as soon as possible. 

Yes, as Marcus mentions, there is now a new build of EPiServer SP3 available via EPiServer Manager. The version is now 5.1.422.267. We recommend everyone that has version 5.1.422.266 installed to upgrade to the new version.

If you now install a new SP3 site you'll always get version 5.1.422.267.

How come EPiServer doesn't provide more information about the upgrade and installation?

I would like to know the manual steps for upgrade SP2 to SP3.

This can be fixed with a custom http module doing this:

public void Init(HttpApplication context) 
{
    EPiServer.Web.InitializationModule.Initialize(EPiServer.Configuration.EPiServerSection.Instance, EPiServer.Configuration.Settings.Instance);     
    if (!EPiServer.BaseLibrary.ClassFactory.IsRegistered(typeof(EPiServer.Diagnostics.ITransformer)))     
    {
        EPiServer.BaseLibrary.ClassFactory.RegisterClass(typeof(EPiServer.Diagnostics.ITransformer), typeof(EPiServer.Diagnostics.DefaultTransformer));     
    }
}

See this post:

I cannot find the Application_FirstBeginRequest event in EPiServer.Global.

Does anyone know where it is located?

This atleast works in EPiServer 5.2.375.133, I am not sure about other versions.

The event Global_Application_FirstBeginRequest is not located in EPiServer.Global but EPiServer.Web.InitializationModule

So the handler should not be registered like this
EPiServer.Global.Application_FirstBeginRequest += new EventHandler(Global_Application_FirstBeginRequest);

But rather like this
EPiServer.Web.InitializationModule.FirstBeginRequest += new EventHandler(Global_Application_FirstBeginRequest);

Hei, 

I am getting the same error when upgrading the site from CMS 5 SP3 to CMS R2 SP2. 

Any suggestions ?
