Object Reference Error When Creating a Dashboard in DevExpress 22.1

[Muzafferozen]

I hope this message finds you well.

I am writing to report an issue I encountered after upgrading DevExpress from version 18.2 to 22.1. When attempting to create a dashboard in the designer, I am met with the following error:

Object reference not set to an instance of an object.

at Xpand.XAF.Modules.ModelMapper.Services.ModelBindingService.BindToModel(IModelNodeDisabled modelNodeDisabled, Object instance)
at Xpand.XAF.Modules.ModelMapper.Services.ModelBindingService.BindTo(IModelNodeDisabled modelNode, Object instance)
at Xpand.ExpressApp.XtraDashboard.Win.Controllers.DashboardDesignerApplyModelController.OnDashboardDesignerOpening(Object sender, DashboardDesignerOpeningEventArgs e)
at System.EventHandler`1.Invoke(Object sender, TEventArgs e)
at Xpand.ExpressApp.Dashboard.Controllers.DashboardDesignerController.OnDashboardDesignerOpening(DashboardDesignerOpeningEventArgs e)
at Xpand.ExpressApp.XtraDashboard.Win.Controllers.DashboardDesignerController.DashboardEditExecute(Object sender, SimpleActionExecuteEventArgs e)
at DevExpress.ExpressApp.Actions.SimpleAction.RaiseExecute(ActionBaseEventArgs eventArgs)
at DevExpress.ExpressApp.Actions.ActionBase.ExecuteCore(Delegate handler, ActionBaseEventArgs eventArgs)

This issue did not occur in version 18.2 and only began after upgrading to version 22.1. The error seems to be related to the Xpand.XAF.Modules.ModelMapper.Services.ModelBindingService class.

I would appreciate any assistance or guidance you can provide to resolve this issue, as it is currently hindering our ability to effectively utilize the dashboard designer.

Steps to Reproduce:

Upgrade DevExpress from version 18.2 to 22.1.
Attempt to create or edit a dashboard in the designer.
The error message appears, preventing further actions.
Additional Information:

We are using XAF with Xpand extensions.
The error occurs during the dashboard designer opening process.
Thank you for your attention to this matter. I look forward to your prompt response.

Best regards,

Xpand.ExpressApp.XtraDashboard: 22.1.602.0
Xpand.Extensions.XAF: 4.221.11.0

maybe @CWolffIF encounter something similar in the past?

@Muzafferozen provide a sample using the latest source failing the same. Like this nobody will spent its valueable resources to resaearch it cause it can be anything e.g. just a corrupted Xaf model could cause it. Spending your time to prepare a sample it will teach you a lot e.g. does it work on 22.1 on empty solution having the same modules? does it work in 24.1 asking support to answer those questions for you is not realistic.

Thnks for the understanding
