Adobe Interactive form, send as PDF

Hi All

I have created an Adobe Interactive form using Webdynpro.

When I run the Webdynpro application, the initial Interactive form is generated.

When User fills the Interactive form and click on Submit, the filled form should be either saved or send to the user.

I have  got the XSTRING of  PDF in the pdfsource node,but it is initial.

Again when I save that filled form using  CL_WD_RUNTIME_SERVICES=>ATTACH_FILE_TO_RESPONSE, the form is initial, cant see any data in that.

How can I get the filled interactive form ? and then I have to attach that PDF with the workflow.

Regards

Anup
