Hi all,

    One of our customers requires a Java application implementation
of our client-side software, instead of our existing web-based
implementation.

    In order to simplify the process and to reuse the scripts we have,
I have decided to use Javascript scripting. As I am quite new with Rhino,
my implementation technique might be wrong.

    I am creating a shared scope object that hosts system functions. It
is also primarily used to share variables and functions across different
windows.

    Next, for each opened windows, I created a scope for them individually.
This way, scripts parsed are not directly accessible from other scopes.

    My problem is, sometimes we need to access child windows to access
their properties and invoke their method. This was ok with Mozilla or
Internet Explorer, as I can get a reference to a window I create
(var wnd = window.open(...);), and access the variables and the methods as
well.

    This is different in Rhino however, although I can access their
variables,
invoking a child method runs the method in the caller's scope, not the child
scope. Is there any way to implement this?

    Thanks in advance.

Regards,
    Kok Hoor
