                     src="${resource(dir: 'images', file: 'update.gif')}" />Description
Attributes
- value- The caption of the button and name of action when not explicitly defined
- src- The source of the image to use
- action(optional) - The name of the action to be executed
You cannot use multiple actionSubmitImage tags within the same form and have it work in Internet Explorer 6 or 7 unless you add some custom JavaScript. See this page for a bit more information and a workaround.
