JOSE JAVIER COLUMBIE
Who is ready for our monthly community standup? UI customizations, here we go.
A lot of great links about XAF Blazor in this issue and some cool experiments as well.
There is no better time to be a XAF developer than right now and if you review all the links you will see that we have a lot of great support tickets. Now is the perfect moment to get in the habit of reading all new questions the community is posting on the support center and specially with Blazor evolving it is definitely a highlight on my day.
Ok, right to the point and to the issue. See you guys tomorrow and as always XAF Out!

Integrated Security| DevExpress Support
What queries does the security system generates?
When a user saves changes in an existing object, the security system checks this object two times:
The first time it checks the object in its unchanged state to make sure that the user has rights to modify it.
The second time it checks the object in its changed state to make sure that these changes don't violate security rules.
If the object is new, the security system skips the first check.
