Portal 2 - Using Workflow portlet with workflow with Input parameter

We are on Flow Version using Portal 2

I have a Workflow portlet that is listening to a Filter Portlet. I have setup a Datasource on the Workflow portlet to fetch data, and I have a Interation Workflow that has a Input parameter. However, I can’t seem to get the Workflow portlet to pass any data to the user Workflow via the input parameter.

Has anyone tried using Workflow portlets with flows using Input data?
