So we want to invest in creating a print button that just calls javascript window.print(). Putting this in a customer interface component won't work, right? The interface component cannot access outside it's context.
What are other options? Deploying a servlet with print that takes in the url for the form? But then the form url has to be known each time and won't work for printing tasks, right?
