I am not clear about what you are doing. The client code you show
includes no byte array. Is the byte array on the server? I would have
to assume it is. Do you verify at the exit of your service method that
the string as contained in the DOM is the length you expect? Where in
the provider do you check the string to see it is 5k? Are you checking
the string still in the DOM, or as serialized? If you are looking at
the string while it is still in the DOM, I'm not sure what could have
gone wrong.
