Using Workflow to create an InfoPath item in a Forms Library

Hi Experts:

Here is my situation:

I have a MOSS 2007 server with list A (regular sharepoint list) and List B (InfoPath form library with a published form)

This is what I am trying to accomplish using SharePoint Designer:

• List A is just a basic list
• User changes a column in list A to a specific value
• A new form needs to be added to the forms library B

SharePoint designer Workflow will not create a valid xml file in the List B forms library. It just creates an invalid file based on the .xsn file template.

Does anyone have any experience creating a valid xml form in a forms library using SharePoint Designer workflow?

I can't migrate to 2010 so that is not an option.

Thanks for all your advise.
