javascript to javascript communication after C++ callback

[Greg Thokle]

I have a callback scenario where a js object gets called by a C++ object
and then that js object must call a function in another .js script.  I
am unable to get the js object to recognize the function in the other
.js script.  Any ideas?

- I have a .xul script that includes two scripts a.js and b.js.

- a.js has two functions: create and notify.  The create method
instantiates the IDummy interface defined in b.js and also instantiates
a C++ interface.

- a.js calls a method of the C++ object and passes the Dummy object
created from b.js

- The C++ object then calls an dummyMethod of Dummy in b.js which then
calls the notify function of a.js

I have gotten everything to work upto b.js calling the notify method of
a.js.  When I add code to get b.js to know about a.js' notify method and
start mozilla, I get "[Exception... "[JavaScript Error: "notify is not
defined".  The line in question is shown below from b.js.


function Dummy() {
     this.notifyFunction = notify;  <-- Causes error when loading
mozilla.exe
}

Dummy.prototype =  {
    dummyMethod: function () {
        this.notifyFunction();
    },
...
}


Thanks,
