Thanks Cathy - that gets me a lot closer to understanding how this works but I'm still in murky water.
I have a copy of the report listener foundation class on a form where I intend to modify the action in the render method. I have a button on the form to run the report. I'm stuck on how to tell the report to use my version of the listener.
