How to read Exception decoder
Posted: Fri Aug 12, 2016 6:58 amHi All
I have been testing the WifiAccessPoint code I have written. It is essentially the same as the example supplied.
When I i submit a page with some form avriables all works well. However, I have noticed that when i plress refresh on the webpage. It throws an exception.
So I downloaded the exception decoder. this is the result:
My question is this. Where to from now? How do I make sense of this decode? Would it be the topmost entry that threw the exception? How do I go about debugging this?
