Ironruby core - Mar 2010 - How do I pass an ExpandoObject from C# into IronRuby?

I tried to send this question earlier, but it did not appear to go through.
Shortly after I tried to send it the first time, the "Consuming
DynamicObjects in IronRuby" thread popped up. It seems likely that the two
issues are related, but as my situation is a bit different and results in a
different error message, I thought it would be a good idea to resend this
question. Note: I am using .Net 4.0 RC and the "CTP for .Net 4.0 RC"
release of IronRuby...


So I''m finally getting around to testing IronRuby/C# integration and
hit a stumbling block. Let''s say I have the following class in Ruby:

 

class HandleMoveRequested

                def handle(msg)

                                System::Console.WriteLine "Moving character
to " + msg.x.to_s + "," + msg.y.to_s + "."

                end

end

 

As you can see it is a simple message handler that expects an object that has an
"x" and a "y" property. Now say I have the following C#
code:

 

dynamic handler = ruby.HandleMoveRequested. at new();

dynamic msg = new ExpandoObject();

msg.x = 1;

msg.y = 2;

handler.handle(msg);

 

Creating the handler instance works fine, so I won''t bore you with the
details of that, but for some reason the last line throws an
InvalidOperationException with the message "unbound variable: value".
Everything works if the message is a Ruby class that I create manually, but
I''d love to be able to just create a fully dynamic object (such as the
ExpandoObject) here and pass it in. Is this just not possible?

<http://stackoverflow.com/questions/2365668/how-do-i-pass-an-expandoobject-from-c-into-ironruby/>Essentially,
Tomas fixed this, and if you build from source now, your code will work.
Thanks
