                                  • Debug the attached project and execute the Action from the Tools category:

                                    using System; using DevExpress.ExpressApp; using DevExpress.ExpressApp.Actions; namespace T499468.Module.Win.Controllers { public class T499468 : WindowController { public T499468() { var popupWindowShowAction = new PopupWindowShowAction(this, "T499468", "Tools"); popupWindowShowAction.CustomizePopupWindowParams += popupWindowShowAction1_CustomizePopupWindowParams; } private void popupWindowShowAction1_CustomizePopupWindowParams(object sender, CustomizePopupWindowParamsEventArgs e) { throw new Exception("T499468"); } } }

                                    This is specific to the debug mode only; everything operates correctly when running in Release mode without the attached debugger.

                                  This still seems to be an issue, or at least it's just moved.

                                  Create a BO with a RuleRequiredField
                                  Click the New action to create a new object
                                  Without making changes, close the detail view, when prompted to save changes, say yes

                                  The Validation exception will occur, then terminate the application.
                                • Thanks for your update, Nate. We'll check this scenario and inform you of our results.
                                  Would you please also specify the exact XAF version you tested?

                                  Working on repro project. It's been... challenging.
                                • OK. We look forward to hearing from you.

                                  Oddly, it's caused by another unrelated class. But seems to conflict somehow? Maybe you could tell me what's up?

                                  In Program.cs the call to TestClass.Instance.MyProperty is what will eventually cause this. More specifically, it's that I create and dispose of a WebBrowser control in this class to get the version.

                                  Thank you for the update.
                                  I have investigated this scenario and found that it is caused by the Visual Studio and .NET Framework specifics.
                                  The Application.ThreadException event handler is not called if a Control object was created before a handler is added to this event:

                                  static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Control c = new Control(); //Comment Me Application.ThreadException += Application_ThreadException; Application.Run(new Form1()); }

                                  See the attached project for more details.

                                  It would of course be something stupid wouldn't it :) Thanks, Dan!
