Re: GWT.runAsync and Command Pattern

I had exactly the same issue and in the end abandoned the command
pattern. I managed to come up with an approach using standard RPC that
gave me most of the advantages i.e. centralized error handling,
session expiry and the ability to cancel all currently active calls.
Even using standard RPC You still need to be careful that your RPC
service classes don't get too big because as soon as the proxy is
created this will include all the dependencies for all classes
referenced as arguments via the service functions.
