ASPxGridListEditor - FormatException is thrown when selecting an object in a lookup ListView shown from an aggregated collection

[Web] ObjectPermission DetailView throws FormatException from Guid

created 8 years ago (modified 8 years ago)

Hello,

I am experiencing an issue when accessing an ObjectPermission in XAF via the Web interface. I have tested this in a new project, this also shows the behavior, which leads me to believe this is an issue in XAF or one of the web controls. I have not found anything referencing this issue in the change logs, leading me to believe it may also be present in the newer XAF versions.

The exception thrown is a FormatException, claiming a GUID is incorrectly formatted. I can't find any information on which field it is referencing. The issue can be reproduced in a new XAF project with the Security System module used. The simplest way is to access the Role 'Default', then opening the permission for the 'User' class in a nested view, and then opening the single ObjectPermission. This will throw the exception.

Here is the stack trace for the exception:

The loaded assemblies are simply the default XAF assemblies as I have used a completely new project to reproduce this.
