Hi Jimmy,
I have an existing form library that users have been submitting forms to, but the design is too unwieldy. As a result, I've now split the form into four separate ones and hence now want to use these instead of the existing big form. The problem began with users being unable to submit forms and the error message received then is the same I'm still getting.
No longer at work so cannot attached a screenshot, but error is
System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Exception: Exception Code: I0001
Exception Message: No DocumentType found for ''.
I followed the blog posting I found and created an XML file with the same name and the XSN and the document type, but still received the error. To be honest, the last time I tried this I didn't do that - does it have to be an XML file loaded as a resource or can I simply create a field within the form and store the name in there? Should it be name of the file including the extension or just the name of the content type attached to the form library?
