Hi Dean, In my earliest prototypes with GWT RPC, I decided I didn't want to bother with failed calls, so I implemented my own AsyncCallbackAdapter which stubs out the onFailure with a Window.alert(). Then I extend that for the specific RPC cases. Strangely enough, I haven't had to revisit that decision. I think the same approach would work for you, except your default onFailure would inspect the exception to ascertain that it represents a session timeout, and then effect the location change to the login page. There would of course be a one-time effort to put this in place of what you have now. And you would still need to "educate" developers to always extend the adapter when implementing new remote services.
