Perhaps I'm doing something wrong, can I just extend
MultiWordSuggestOracle to do what I want by overriding
requestSuggestions ? I tried doing so but I get the following error:
Unable to load module entry point class xxx (see associated exception
for details)
com.google.gwt.core.client.JavaScriptException: (TypeError): Object

Where xxx.java:148 is "_input = new SuggestBox(_tokenOracle);" and
_tokenOracle is the class which extends MultiWordSuggestOracle. I
haven't done anything fancy with TokenOracle yet either:
public class TokenOracle extends MultiWordSuggestOracle {
public TokenOracle() {
super();
}
public TokenOracle(String whitespaceChars) {
super(whitespaceChars);
}
}
