Simple Hello World Grails Form Submission

Question

I am new to Grails and I am trying to get a very simple example to work. I should just submit a form and display "Hello World" on the screen. It consists of the following controller: ``` package surface class SearchController { def index() { render(view: "search") } def result() { render "Hello World" } } ``` and a view, with the form: ``` <%@ page contentType="text/html;charset=UTF-8" %> ``` When I click on "Ask" I get a 404 error but the browser correctly accesses "/surface/search/result". When I enter that address directly without using the form the "Hello World" appears correctly. This is probably a no-brainer but I seem to be unable to find out why this does not work from the documentation.

Accepted Answer

Complementing the @Tom Metz answer, what you need to keep in mind in the Grails controller structure is that every public method is considered an action. This action is mapped to a url. In your example will exists `/search/index` and `/search/result` (controller + action).

The documentation of the `g.form` is corret, since this says that;

url (optional) - A map containing the action,controller,id etc.

So to correct your view you can set the action as commented or you can adjust the way you use url:

```
<g:form name="myForm" url="[action:'result',controller:'search']">
```
