[xwt-users] Passing arrays in xmlrpc calls

Hello,

Is it possible to pass arrays in xmlrpc calls from within xwt ?

I have a small xwar sample that I run locally against an xmlrpc server.
It successfully invokes a procedure that echoes back some string. Then
It calls a procedure to compute the sum of an array of doubles
But this seems to fail. The xwt logfile shows the following message
during the 2nd call:

"XMLRPC:  at main.1:33
              XMLRPC: attempt to send object of type java.lang.Object
via XML-RPC"

I test the xwar locally with the latest stable xwt engine (0281)
I get the same results for Windows and Linux.
For xmlrpc server I use the "HelloServer" demo program from 
the xmlrpcpp project - See http://xmlrpcpp.sourceforge.net.
(Below you find the main xwt routine+output from the xwar)

Thanks for any feedback

Tom
