Hi,
ok, I opened my app in a browser, then made a change to a class
implementing IsSerializable:
I made a change to the class Announcement, which in turn uses an enum
AnnouncementType.
Then I redeployed the app and used the app within the still open browser.
I expected my exception handler to show the nice message, but it simply
showed "The call failed on the server."
The server's log showed a SerializationExeption (see below): The enum
AnnouncementType was not assignable to IsSerializable.
And indeed, AnnouncementType was not implementing IsSerializable, that's
correct. But this code is running for years.
Why does this exception occurr now?
The stacktrace below does not contain one of my methods. So how can I catch
this exception and show a more user friendly message?
Magnus
