I'm having an issue with my GWT/GAE app. Whenever it returns one
specific kind of serialized object from the backend via RPC, I get
this exception and a failure. I know the code is working on the
backend (it'll be included under the stack trace).
(Exception)
com.google.gwt.core.client.JavaScriptException: (TypeError):
Cannot call method 'nullMethod' of null
arguments: nullMethod,
type: non_object_property_call
stack: TypeError: Cannot call method 'nullMethod' of null

}
If you have anything else you want me to post, I'll be happy to
provide it.
Thanks!
