If you've found yourself in this situation, you're not alone. Many developers encounter challenges with refreshing their widgets in the Guidewire environment, specifically when using Gosu. In this guide, we will guide you step-by-step on how to refresh a ListView widget so that you can ensure your application displays the most current data. The Problem: Refreshing a Widget When you're working with ListView widgets, you might find that after an action, such as data entry or a button click, the displayed data doesn't reflect the latest updates. This could be due to using outdated data from the database or another resource that's supposed to be updated. Fortunately, there are ways to trigger a refresh of the widget. The Solution: How to Refresh Your ListView Refresh Button One of the simplest methods to refresh the data visible on your ListView is to implement a "Refresh" button. This button facilitates data reloading from the source whenever it is clicked. Here's how to do it: Locate Your Screen Configuration: Identify the PCF (Page Configuration File) where your ListView is defined—this could be similar to the Underwriting Rules Import/Export Status screen in PolicyCenter.
