"parameter is incorrect" error when adding submit to web service

[scottw]

I am getting an error "The parameter is incorrect" when trying to open a form
after publishing it using msi install. It is full trust form. This happens
only when I try to add a submit to web service. When I remove the submit to
web service, everything is OK. It is strange since I can add the web service
submit with no issues. I tried to preview the form after that, but I get
error "InfoPath cannot open the selected form." So, I thought maybe I need to
publish the form to test the web service. I do have some simple code in the
form using the older InfoPath 2003 syntax. The web service is using a dataset
parameter. I used fiddler and when opening up the form from the published
location, it is not looking at the web service, so I know it is not an issue
with any code in the web service. I am at a lost since the error is too vague.
thanks
