Hello
Gary,
Thank you for your suggestion. I'm afraid we could not modify the live demo to throw an exception.
Also, we have an explicit check on the click of the Load button here:
As to the case you mentioned, it is possible to avoid the exception inside the state serialization provider if you have one. It would be something like this:
This will work if you return an empty string from the LoadStateFromStorage method in the storage provider.
I hope this helps.
Regards,
Daniel
