exception: encodedRequest cannot be empty

[Alejandro D. Garin]

Hi,

I'm getting this exception on an application hosted in java appengine. I can't reproduce the problem because it seems to happend at random and in differents situtations.
Any ideas of what is going on ? Should I post to the appengine forum?
Thanks

I'm using gwt-sl 0.1.5b and GWT 1.6

Hello Alejandro,

welcome to the internet.What you're seeing is just a network failure and
there is not much you can do about it.
