Grails: Pass Params from Controller to Controller at end of Webflow

Is it possible to pass 'params' in a redirect at the end of a Webflow? Basically the purpose of this variable or param passing from controller to controller is this, I want to have a variable or ${param.xyz} available on the view page only if the flow has been completed. 

 class Example1Controller{
    def startFlow = {
        begin {
        ....
        }
        ....
        ....    
        finished {
            action {
                flash.message = 'success'
            }
            redirect(controller: 'example2', action: 'myaccount', params: [author: "Stephen King"])
        } 
     }
  }

OTHER CONTROLLER

 class Example2Controller{
     def myaccount() {
         def here = $params.author
         return [me:here]
     }
 }

GSP VIEW

 <html>
     <body>
         <g:if test="${params.me}">
             <p>This is what I want to display: **${me}**</p>
             <p>But it must come from the first controller, from the flow.</p>
         </g:if>
     </body>    
 </html>

Basically the purpose of all this variable passing from controller to controller is this. I want to have a variable or ${param.} available on the view page only if the flow has been completed.

If I remember right, we did this before but we used the flow scope/ flow variables. Something like:

def myFlow = {
    fin {
        redirect: (controller: "xxx", action: "yyy", params: [someValue: flow.someValue])
    }
}

Then, in the receiving end, something like:

def yyy = {
    [ aaa: params.someValue ]
}

You can use hiddenField .

<g:hiddenField name="myField" value="myValue" />

you can pass value from Example1Controller to Example1Gsp(as hideenField) and from that GSP you can get value in your Example2Controller.
