Form Server Submit Form QPAC - Not pulling data

Question

Hello everyone,
I wanted to see if anyone has encountered problems using the above QPAC.
My situation is as follows
1) User sends PDF back. PDF is sent back to workflow as a PDF (not XDP)
2) Form Server Submit Form is setup to extract the data from the form and put it in a document variable
However, that is not happening. I do know that the document is not broken when it is received from the Email Receiver QPAC (I've used the Avoka Document Extract QPAC to test the form itself) however for whatever reason, the variable is still empty after it is processed.
Any thoughts are appreciated!
Thanks,
Rob

Hi Nico
Some background. When Adobe first launched LiveCycle, the first capabilities they needed to expose was encapsulated as Forms Server, and it provided:
1. Rendering a form. This would take a PDF or XDP file, plus some xml data, merge them together, and produce a PDF file.
2. Handling a form submission. This would take the data from an http request coming from a Submit button on a form, process it, and extract the XML data.
The Forms "Submit" QPAC is basically the submission API encapsulated as a QPAC. If you want to know exactly what it does, the best place to look is the LiveCycle Forms documentation.
So, to your question:
If a document variable contains a PDF form, you can use the Form Submit QPAC to extract the XML data.
A form variable is really just the XML data for a form, plus a reference to the PDF or XDP file that should be used for displaying the data - so if you assign the extracted XML to the appropriate node in the form variable, it should work.
I hope this long ramble is helpful.
