Bummer! resourcetrysuggester.js added new fields to a Java type, so I 
thought it should work.

This does sound like an acceptable work-around, however, it doesn't seem 
to work:
TypeError: Java.super(filter).fireMatchNone is not a function

I guess there is no way to call protected methods from JavaScript then? 
Well, I guess reflection will work.

Kind regards,
