I have a controller that needs to return a 404 page and status code on certain conditions. I can't seem to find out how to do this in Grails. A coworker recommended this method:

```
response.sendError(HttpServletResponse.SC_NOT_FOUND)

```

which works perfectly fine, but it's not very Grails-like. I know Rails' render method take a status argument, but Grails' render has no such functionality. Is there something I'm missing, what's the best way to accomplish this?
