Re: ProjectTracker: What purpose fulfills the ProjectResourceEditCreator class?

I'd actually like to raise this issue again.

I'm looking at the current (4.3.12) version of the ProjectTracker project from a WPF-over-3-tiers perspective. I also have the eBooks for CSLA 4.

The UsingCsla4-05-WPF-SL.pdf book (Rev 0.4 (draft)) states the following:

The ProjectResourceEditCreator type is not used by the smart client applications covered in this ebook. For a full discussion of this type, please refer to the Using CSLA 4: ASP.NET MVC ebook.

However, when I run the WPF client in debug and add a resource to a project the following method is being called:

class ProjectResourceEditCreator

public static void GetProjectResourceEditCreator(int resourceId, EventHandler<DataPortalResult<ProjectResourceEditCreator>> callback)

{

DataPortal.BeginFetch<ProjectResourceEditCreator>(resourceId, callback);

}

I'm about to develop a WPF application making asynchronous calls over WCF to a middle tier, and I'm puzzled as to what is the advised pattern.

Thanks

Mark

Good to know, thank you!
I never looked inside the UI books so far....

It is described in the Using CSLA 4 ASP.NET MVC book (and with figures too):

"The ProjectResourceEditCreator exists to support asynchronous smart client applications
and stateless web server applications. This type isn’t used by synchronous smart client
applications"

ProjectTracker: What purpose fulfills the ProjectResourceEditCreator class?

Hello,

I am investigating a little bit within the project tracker sample application.
Can someone explain to me for what the separate class ProjectResourceEditCreator is for?

Sure, I see it creates ProjectResourceEdit instances and fetches them from the database.
But why is this separate implemented and not by factory methods within ProjectResourceEdit?

Thanks for clarification,
Alexander

btw: is there any overview documentation about the PT sample?
