JOSE JAVIER COLUMBIE
Hello XAFers,
We were waiting to have XAF running in Linux to send this issue and I am excited to say... it runs like a charm!!! (Check the video in the links below).
Also don't forget we have the XAFers Community Standup tomorrow where besides a couple requests about localization, controllers, etc we will be doing a Live QnA, so get your questions ready. You will have DevExpress MVPs Manuel Grundner, Dave Hesketh and Joche Ojeda ready to share their experience developing XAF applications for many years, so don't hold back, there is not stupid question. As always, a beer or a coffee is highly encouraged.
Lastly, I want to thanks everyone who has subscribed to XAFers Weekly (we are almost 300) and joined the Facebook Group (almost 430 members). What started as a place to share/save interesting links has become an awesome platform to discuss, collaborate, help and grow. Thanks again for the support, and the amazing response.
Until next week, XAF out!

XPO - Updated .NET Core Examples, Performance Benchmarks for EF Core 5.0 and More (v20.1)
It is always nice to see the benchmarks for XPO and EF and to validate we are using the best ORM in the world (you can't notice I am biased). Also a few great support tickets about unit testing, troubleshooting Reentrancy or cross thread operation detected and a console version of the XPO Profiler that I am dying to try. I will let you guys know after I do :)

Non-Persistent
How to edit a collection of Persistent Objects linked to a Non-Persistent Object
When a Non-Persistent Object contains a collection of persistent business objects, we want to edit linked objects right in the list view either in in-place mode or in ListViewAndDetailView mode. Also, when a linked persistent object is edited in a popup detail view, we want to see changes in the source list view after they are saved. This link has the solution.

How to implement CRUD operations for Non-Persistent Objects stored remotely
This example demonstrates a possible implementation of editable non-persistent objects that represent data stored remotely and separately from the main XAF application database. These non-persistent objects can be created, deleted, and modified and their changes are persisted in the external storage.

How to refresh Non-Persistent Objects and reload nested Persistent Objects
It is often required to cancel changes made to Non-Persistent Objects in a view. When a Non-Persistent object has links to Persistent Objects, it is often required to reload these linked objects too. However, the built-in Refresh action has no effect in these scenarios by default. How can we achieve this?

Modules
XAF Modules API of the Week - Charts - YouTube
One module each week. First, all official DevExpress modules, then all community modules, LLamachant modules, Ultra modules, eXpand and more…
This week we are reviewing the Chart Module.

PositionInListView Module - eXpandFramework
The PositionInListView XAF module, allows to control how objects are positioned in a ListView from the end user. This is a platform agnostic module that is designed to sort a ListView based on a existing Business Object member. I have not tested it but it is on my list for the XAF Modules API of the week and it looks really handy. Great work by the eXpandFramework.
