@Documented @Retention(value=SOURCE) @Target(value=METHOD) public @interface GWTConfigCallback
gwt.js
(a), which may optionally be placed in the vote-server's
publicConfig
directory. An empty template (b) of gwt.js
is
provided for reference, along with a working example (c) from the development
vote-server. Unlike an initialization callback, a
configuration callback is invoked immediately on module load.
