title: Can i call an controller action with POST-params from another controller as method?
body: <p>I've a controller and some actions within. Am i able to call these actions as methods from another controller as if i would call this action with post params?</p>
  
  <p>I'm using the grails paypal plugin and it has an action called "buy". I don't want the user to POST the product-data and information to the buy-action. I already know the things the user wants to buy and i want to call the buy-action within my Controller as i would call a normal method and then i want to redirect the user to paypal (to the url, the buy action returns).</p>
  
  <p>I'm using grails 2.0 and newest paypal plugin.</p>
