title: How to extend/override controller actions of plugins?
body: <p>The plugin (Nimble 0.3) I am using in my grails application, includes some controllers and associated actions. <strong>I want to change (slightly) some actions behavior</strong>, and I was wondering how I can achieve that.</p>
  
  <p>Can I create a <strong>child controller</strong> that inherits from my plugin controller and override some of the action implementation?</p>
  
  <p>Or, can I create another Controller <strong>with the same name</strong> as the plugin controller but located in a different package? </p>
  
  <p>Well actually what I really need to understand is : <strong>how Grails determines which controller action to call</strong> when there are name conflicts ?</p>
