I have a server-side asynchronous web method that I built using advice from this article. http://msdn2.microsoft.com/en-us/library/aa480516.aspx
The web method works great, until I add the soapServerProtocolFactory configuration tag that adds the WseProtocolFactory to the server side. It throws a null pointer exception error. But that error comes from the WSE trying to access the HTTPContext before it has been given back. I don't know what the real error is. Has anyone ran into this problem? Does WSE 3.0 support the server-side asynchronous web method model? Here is a copy of the error I get.
Type : System.NullReferenceException, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Message : Object reference not set to an instance of an object.

TargetSite : Microsoft.Web.Services3.StateManager GetOrCreateSessionStateFromHttpContext()
Stack Trace : at Microsoft.Web.Services3.WseProtocol.GetOrCreateSessionStateFromHttpContext()

Any help? Notice this is not calling a web method asynchronous , this is a server side asynchronous web method.
