The new Refresh Button Widget released with KNIME 4.4 (July 2021) lets you build complex interactive views where you can partially re-execute the workflow inside the component. This new framework enables you to build with visual programming data apps that otherwise would require a team of full stack developers. To learn how to use the node we built a collection of examples. In this workflow we learn how to: build a search engine which triggers complex SQL queries in the backend. Download the workflow and open the component view (Right Click > Open Interactive View). To inspect how the workflow inside the component looks open the component: Right Click > Component > Open
