Adaptor notification service issue

When I create an adaptor notification service using developer it generate automatically generate document for notifications which publishable at the time. But it doesn’t start working when you enable the polling.

When I restart IS sever it begins to work but with error that the document is not publishable. If you go and see the auto generated document in developer you get to know that it is not more publishable… and the fields are read only mean you can’t make it publishable again.

I tried many times, but every time after IS get restarted this document become unpublishable any clue? I am working on web method 7.1
