Grails redirect, forward and render alter view and shows Grails banner/template

Question

When I redirect to another page, Grails alters the screen by adding a banner that looks like this:

Here's a snippet of the code:

def login() {
    def user = userService.login(params.username, params.password)
    if(user){
        chain (action: "main", model: [user:user])
    }else{
        redirect (uri: "/")
    }
}

def main() {

}

I tried using forward and render instead of redirect, but the banner is still there.

I am not sure if I understand you, but maybe you are rendering a gsp which has the meta layout included in the head block.

<meta name="layout" content="main">

Just delete it. If I am right you can find more info here: grails layouts
