THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
The ajax a template is used to make asynchronous calls to the server when the user clicks on the a href link. It is useful when you need to communicate information back to the application from the UI, without requiring the entire page to be re-rendered. An example would be removing an item from a list.
Remember: the content returned by the href attribute must be JavaScript. That JavaScript will then be evaluated within the webpage. If you only wish to publish an event to the topic specified, then simply return no result (or NONE) from your action.
