I have a dynamic pdf form that I'm trying to have invoke a process service via the soap endpoint. In the process I'm taking the data from the form merging it with a template, reader extending it and mailing it to a person selected in the form. My problem is I can't get the data from the form into the service. In fact I can't even invoke the service from the form. I was thinking that since I have some input process variables, when I do data connections in designer and connect to the service, I see the invoke operation, and select it, and I then see my input variables, bind them to the form fields, and pass the form data in as a parameter. I've tried different datatypes, but nothing is working. My question is what exactly are the steps to get data from a pdf form submitted outside of workspace, to invoke a process using that data? Should I be using a document type variable, or xml? Any help is appreciated.
