XML : Grails render XML invokes another action from the same controller

I'm working on Grails 2.4.4 and have an action that renders this way:

  def subjects = [...]  render(contentType:"text/xml", encoding:"UTF-8") {    'result' {       'patients' {          subjects.each { person ->             delegate.patient {                uid(person.uid)                firstName(person.firstName)                lastName(person.lastName)                ...             }          }       }   ...    

On the same controller I have a 'getPatient' action, and that action is invoked when the XML render is processed, from this line: delegate.patient

I tried with "delegate" (it seems the delegate there is the controller itself), I tried also quoting the node like 'patient' { ... }, but getPatient is called every time.

Is there a way of making this XML render work without changing the getPatient action name?
