JSON Format returned from Ext.Direct (TreeLoader component)

[Enygma]

Hi I'm trying to update an application to using Ext.Direct, which was going just fine until I got to the TreePanel.
I'm using extdirect4dotnet.

I took a look at the Tree example for Ext.Direct and the response comes back as a JSON object i.e.:

{
    "type": "rpc",
    "tid": 2,
    "action": "TestAction",
    "method": "getTree",
    "result": [etc...]
}

However, when I call my getTree method using extdirect4dotnet all the responses come back as an array:

[
    {
        "type": "rpc",
        "tid": 3,
        "action": "Tree",
        "method": "GetTree",
        "result": [ etc...]
    }
]

This works fine for regular Direct Method calls where I define my own response handler, however for TreeLoader I don't think you can do that can you? Can anyone point me in the right direction?

Thanks

Result should be an array of objects:

{"type":"rpc","tid":5,"action":"Menu","method":"getTree","result":[{"id":"id","type":"class","text":"Name","code":"WEB401","leaf":false,"expanded":true}]} 

Need a bit more info to tell what could be wrong (complete treepanel code and server side method).
