Thanks, Sukumar
My understanding is that MyLateJavaObject is not represented in
Javascript as an object, so there are limited things we can do with
it. From experimentation:
e.g. you can do this:
var obj = MyJavaObject;
obj.method();
But not this:
var fn = MyJavaObject.method;
method();
It does not exist on the window object:
assert.ok(!window.MyLateJavaObject);
assert.equal('undefined', typeof window.MyLateJavaObject);
I'm not aware of any global object (other than window) in this
implementation of Webkit.
I have not tried finding window.MyJavaObject, which was added before
onPageFinished.
Regards, etc
