Hello, I've been through this problem a few weeks ago with my module that exports nested structures through xmlrpc. Apparently, there's a limitation in the technology itself that makes the nested structures to be overwritten everytime the response XML is parsed, if you look closely, you will notice that this makes sense since the structures are indexed by the name of the field, which is the same for every record. That's the reason of only one row being displayed even though the whole recordset was sent out.
I tried with three different php libraries, even with xmlrpc_decode() that is the official function for decoding xmlrpc responses in php. I didn't find a solution but I ended up using a workaround sending the values using CSV format which was later parsed by the PHP in charge of displaying the data. Regards. Carlos.
