Error openning Modeldifference detail view (no matter if role or user)

[chulanbetra]

Hello, I updated expand to version 20.2.503. I am using couple expand modules as nuget packages, one of them is modeldifference (web and win). I can start win application without problems, but when I try to open detailview of modeldifference object (user or role) I get this error:

Exception occurs while the 'Xpand.Persistent.Base.General.Controllers.CustomAttributesController' customizes TypesInfo: Object reference not set to an instance of an object.

at Xpand.Persistent.Base.General.Controllers.CustomAttributesController.HandleCustomAttribute(IMemberInfo memberInfo, ITypesInfo typesInfo) in D:\a\1\s\Xpand\Xpand.Persistent\Xpand.Persistent.Base\General\Controllers\CustomAttributesController.cs:line 26

It is exactly this var typeInfo = typesInfo.FindTypeInfo(theValue); if (customAttribute is PropertyEditorAttribute && typeInfo.IsInterface) ...

with memberInfo memberInfo = {Xpand.Persistent.BaseImpl.JobScheduler.Calendars.XpandAnnualCalendar-DatesExcluded} and theValue = Xpand.Persistent.Base.General.IChooseFromListCollectionEditor

I see that this code is also being executed when application starts and there is no problem with getting typeinfo for Xpand.Persistent.Base.General.IChooseFromListCollectionEditor. Only when it is running and I open the detail view.

Although I am running on older database with existing data (we are updating application for customer after long time), I tested this on new empty database and the error is present there too (I assume you have to include jobscheduler module as I do).

Thanks for answer

do u have a repro sample? else u may follow my previous answer.

1. Disable the controller with XpandModuleBase.DisabledControllers.Add(typeOf(CustomAttributesController))
2. Copy the source code of the controller to you solution so u can be able to modify it, put it in FIP namespace
3. We need to disable the controller using some static variable once activated e.g. set the var to true and do not call the CustomizeTypesInfo if true.

Hello,

Disabling CustomAttributeController worked for me. As I do not need the controller right now I did not copy any code into my solution yet (will check the modules if they are working).

Thanks.
