I have a page, and on this page I have a select box. I want that when I click on one of the choices in my select box, the selected element is send to a controller, that controller makes a GORM search, when returns it to a template which will be dynamically printed on the screen. Here is my code at the moment, actually I think the action is not even called.
Glad you figured it out. To answer your question about why you should have gotten a 404 (which you would have had you been hitting the controller) is because when you render a view grails goes and looks for a GSP. It would not have found one, so it would have returned a 404 to the browser.
