Re: javascript call to java method doesn´t work in developing mode - but when code is compiled (GWT 2.51)

If have a Class that looks similar like this:

Calling something 'this' is a really bad idea. 'this' is a keyword, and I'm surprised this even compiles (though maybe it's allowed in Java, I haven't checked). That said, in this case, both the argument and 'this' should be the same value so it shouldn't be a problem.

This code is missing a call to $entry() though:

        $wnd.doSomething = $entry(function(someString) {              _this.@com.example.MyClass::doSomething(Ljava/lang/String;)(someString);

        });
