Submitting to 'this' document library

[walter]

Hi,

I'm trying to use the following "How to" with Infopath 2010 and SPS 2010 :

http://blogs.msdn.com/infopath/archive/2006/11/08/submitting-to-this-document-library.aspx

But I always get following error :

The InfoPath formular could not be transmitted.
The eventhandler for "OnSubmitRequest" doesn't work correctly.
The objectlink was not specified to a objectinstance.
onTestForm_web.FormCode.FormEvents_Submit(Object sender, SubmitEventArgs e)
on
Microsoft.Office.InfoPath.Internal.FormEventsHost.OnSubmit(DocReturnEvent
pEvent)
on
Microsoft.Office.Interop.InfoPath.SemiTrust._XDocumentEventSink2_SinkHelper.OnSubmitRequest(DocReturnEvent pEvent)

(Info: The first three sentences of the message were translated by myself
(from german to english))

Any ideas?
