Webform Server supports actions, but with some limitations. Webform Server instructs the browser to automatically refresh a form whenever the user interacts with the form in certain ways. As a side effect of a refresh, action items that are set to occur once will actually occur each time the form is refreshed. Furthermore, actions that are set to repeat will not work properly. Because of this, we recommend extremely limited use of action items.
