There's an RPCSuggestOracle in the old GWT-Incubator project that you can
use as a "template":
https://code.google.com/p/google-web-toolkit-incubator/source/browse/trunk/src/com/google/gwt/widgetideas/client/RPCSuggestOracle.java
See also
https://gerrit.googlesource.com/gerrit/+/master/gerrit-gwtui/src/main/java/com/google/gerrit/client/ui/RPCSuggestOracle.java,
that might be helpful (as an approach to decouple the RPC requests from the
UI/UX handling)
